In short

Business disruption theory from Clayton M. Christensen’s The Innovator’s Dilemma, explaining why successful incumbents fail when “disruptive” tech starts as worse/cheaper, and how incentives from customers and investors push incumbents to ignore it. Episode also includes examples from disk drives and steam shovels, plus steel mini-mills, and ends with Christensen’s proposed responses (wait, buy competitors, or build an internal disruptor).

Guests

No guest interview. The hosts are Jacob Goldstein and Robert Smith, discussing Christensen’s ideas.

Key claims

Incumbents don’t fail because they’re dumb; they fail because they’re “too good” at serving existing customers and maximizing profit margins. Disruptive products often have lower margins and appear “not useful” until later. Customers/investors rationally steer resources away from early disruptive markets.

Notable examples

Sears vs Walmart/online shopping (framed via Christensen); disk drives (“fruit fly” industry evolution); steam shovels (gasoline = sustaining; hydraulic excavators = disruptive); steel mini-mills like Nucor using electric arc furnaces, starting with cheaper “crappy” steel for rebar and moving up to structural beams.

2:57Pushkit. Too quick? No, it was perfect. Pushkit, stop. You got it. This episode is presented by Odoo.

3:17Jacob, today is episode number three in our series on American genius. Writers that changed the way we do business in this country. We had Benjamin Franklin, who created hustle culture in the mid 1700s, right? Ida Tarbell, the reporter who gave businesses a conscience early 1900s. And today, Clayton M. Christensen. Christensen. Christensen. Okay, not a household name, but you've probably seen his book for sale in airports all around the country, The Innovator's Dilemma. Now, Clayton, after he wrote this, he didn't get his face on the money. There are no statues of him. And frankly, I think he would be embarrassed to be on this list of American geniuses.

4:03He was a humble business school professor, if such a thing exists. And yet we live today in Clayton M. Christensen's world because he was the one who popularized the word disruption. Everybody wants to be a disruptor now. The book Innovator's Dilemma influenced Steve Jobs. He recommended it. Jeff Bezos encouraged his managers to read it. Michael Bloomberg, Mark Cuban. It's on all of their reading lists. But beyond popularizing the word disruption, Clay Christensen developed a theory of disruption. Why business history is strewn with the carcasses of failed businesses. Businesses that used to be on top and then were disrupted into oblivion.

4:45Clayton M. Christensen:We've done them here on the show. Sears. Exactly. Sears, number one, biggest building in the world. Where are they today? And there's this question you ask that we probably ask. How did Sears not see the challenge of Walmart or online shopping? You know, were they stupid? Had they lost their touch? Clayton says no. In The Innovator's Dilemma, he argues they were not stupid. There is something in the nature of technological change that makes it nearly impossible for big companies like Sears to adapt. they fail not because they're bad at business. They fail because they are too good at business.

5:21Too good at the game, and then the game changes.

5:24Clayton M. Christensen:I'm Jacob Goldstein. I'm Robert Smith, and this is Business History. A show about the history of business. The innovator's dilemma isn't about how big companies can't innovate, because they totally can. They have money, they have personnel, they have the means to do it. They just choose not to do it, or to do it in a different way. for very smart and sensible economic reasons. And then those companies die. That's the dilemma. That is the dilemma, which we will illustrate today by reading a children's book. I'm going to be the LeVar Burton of business history. Reading Rainbow. Ding. We love to start the show with a swashbuckling profile of an entrepreneur or thinker.

6:06And unfortunately, Clayton Magleby Christensen

6:10Clayton M. Christensen:did not ride the rails with hobos. Did he work as a telegraph operator at age 13? Did not. He didn't get kidnapped by pirates. No time on a ship? No time on a ship. Clayton Christensen had the most basic business school life trajectory I've ever seen. He was born in Salt Lake City, second of eight children, went to Brigham Young University, Rhodes Scholar, Harvard Business School, Boston Consulting Group. It's kind of like going to sea with pirates. No, it isn't. He was a literal— Boring pirates. He was a literal Boy Scout. In khakis. Yes. I bet he was an Eagle Scout. He was an Eagle Scout. And then he spent 25 years as a scoutmaster, den leader, troop chairman.

6:52I mean, true Boy Scout. And even his foray into business was weirdly undramatic. He teamed up with a bunch of professors at MIT when he was at Harvard, and he helped start Ceramics Process Systems Corporation.

7:07Clayton M. Christensen:That's a lot of boring words together. I feel like, do you need process and systems? I don't know if they made the process or the ceramics or the systems, but something happened with this company that gave Clayton pause. And that was his tiny company succeeded. It succeeded wildly. Ceramics process systems was competing with some of the biggest, smartest companies in the world, DuPont, Alcoa. And Clayton's company beat them all. Now, a less humble professor would have said, well, of course. I'm a genius. I went to Harvard Business School. But then he thinks, you know, is that really it? Like DuPont and Alcoa have people from Harvard Business School, hundreds of them.

7:55They have MIT scientists.

7:57Clayton M. Christensen:There must be another reason. They have money. They know their markets. They should win. They should win. This is very admirable that he rethinks this, right? Well, this is the moment I sort of fell in love with Clayton because he decided to actually devote a research project to study why he and his startup company were not special, were not extraordinary. There must be something in the water of business that makes this happen. And when this is like, what, mid-90s? Yes. You know, now it is less surprising to us when some new company comes along and topples an incumbent because this is the world we're living in.

8:35But I think back to the General Motors show where I looked at the biggest companies in America in the mid-90s, and they were all 100 years old. It was AT &T and Philip Morris. And this idea that a little company could beat a big company was not in the air the way it is now. And this is part of the world that sort of Clayton Christensen is helping to bring about, right? Yeah, and his hypothesis was that this David and Goliath dynamic affects all sorts of industries. As he later wrote, why don't you give me this quote here? There's something about the way decisions get made in successful organizations that sows the seeds of eventual failure.

9:13I just want to say that again. It's a little bit wordy, right? But what he's saying is the way successful organizations make decisions is what screws them. Exactly. Which doesn't sound right on its face, right? Because presumably they're successful because they have made good decisions and they'll continue to be successful.

9:30Clayton M. Christensen:And Clayton comes up with this idea with actual data. He studies the disk drive industry for computers. Now. I feel like our audience remembers disk drives. Okay. I remember the big actual floppy ones and the little hard ones that were still called floppy. Well, there was this whole competition then for putting more and more information on your disk drive. Obviously, in computers, you wanted more and more memory. But at the same time, computers were getting smaller from the big mainframe ones. So you wanted your disk drive to get smaller and smaller. And he had a specific reason Clayton did for studying disk drives.

10:07He wrote about how biologists study fruit flies because they're born, reproduce, and die within a single day.

10:15Clayton M. Christensen:So you get a lot of evolution in a small amount of time. Exactly. Jacob, give us this light reading from Clay. If you want to understand why something happens in business, study the disk drive industry. Those companies are the closest things to fruit flies that the business world will ever see. Because the technology was evolving so fast in the 1980s and 1990s that companies could launch in one year, be top of the charts in the next year, and then be gone in the year after that. So Clayton starts collecting all the data for the industry. And when I say all the data, such an Eagle Scout, I mean all of the data, month by month, sales, new products, year after year after year.

10:56And he sort of maps the genome, if you will, of the disk drive industry. And there are so many technological innovations, he finds, that sometimes the innovations make everyone better. He can see how all the companies adopt a new technology and, you know, they can put more information on the disk drive.

11:16Clayton M. Christensen:Sure. So this is not sort of IP protected. For whatever reason, some professor figures something out. Everybody can do something at the same time, more or less. Yeah. It's all one small industry. They're learning from each other. But then sometimes an innovation comes along and boom, the whole market changes. Companies flourish out of this or they go out of business. And so Christensen asks himself, like, what is happening here? And this is his thesis. This is the thesis of the whole innovator's dilemma he's about to write. And that is that there are two kinds of technological innovation. There's two ways to leap forward.

11:51Number one is what he calls sustaining technologies. Sustaining technologies are the things that companies do all the time to get better. Every company gets better all the time. You know, maybe you have different magnetic film that holds more information. Everyone shares this information. Every company gets better. The big companies stay big. Small companies stay small. So that's sustaining technologies. But the second kind of technology Christensen calls disruptive technology. Here it is. Which sounds cooler and is cooler. And it works in this much wonkier way. So every year, some new company will come up with a disk drive that is smaller and simpler and frankly worse than the old disk drives.

12:34doesn't hold as much information, but it's smaller, right? And the old disk drive companies will ignore it. They'll just be like, that's not going to be the thing.

12:43Clayton M. Christensen:It's a worse product. It's supposed to hold information and it holds less information. And then whoosh. Next thing you know, the small company is eating away market share from the big disk drive manufacturer. And all of a sudden, someone else is on top again and again in the disk drive industry. This is surprising, right? This is his fundamental insight. and we'll unpack it more. But I just want to underline the surprise here, which is the company making what in many ways is a worse product is the disruptor. I would tend to think naively, oh, somebody in a garage figures out a better way to do something.

13:16But Clayton Christensen is saying, no, it's not that. Weirdly, it's somebody doing something worse, but cheaper. And we will go through this in detail. I'll explain how this works. But not about disk drives, because I read Clayton's research on disk drives and it's so dense. and there's a lot of like five and a half beats eight and eight beats three and a half. It's really hard to figure out what's happening. But luckily he wrote about something that's a little bit more in our wheelhouse for business history. He wrote about - Cranes. Steam shovels. Oh, steam shovels. Very good. And I have to admit, I was like, oh, steam shovels.

13:51And I didn't know why I was so excited. And then I thought, oh, there was a children's book I had when I was a kid called, I have it here, Mike Mulligan and the Steam Shovel. How old are you, Robert? Very old. This was even after Steam Shovels had gone away.

14:08Clayton M. Christensen:But here, I want you to read some of Mike Mulligan and the Steam Shovel. Mike Mulligan had a steam shovel, a beautiful red steam shovel. Her name was Marianne. Yes. Do I keep going? Yeah. Okay. It was Mike Mulligan and Marianne and some others who dug the great canals. You didn't tell me there were going to be canals. Love canals. We gotta do a canal show for the big boats to sail through. Yes. Do I keep going? Yeah. You're gonna like this one. And it was Mike Mulligan and Marianne and some others who dug the deep holes for the deep cellars of the tall skyscrapers in the big cities. Classic children's writing.

14:44Beautiful. Then along came the new gasoline shovels and the new electric shovels and the new diesel motor shovels. Disruptive innovation. And took all the jobs away from the steam shovels. Mike Mulligan and Marianne were very sad.

15:01Clayton M. Christensen:I'm going to interrupt you here, cliffhanger, on the steam shovel. But I wanted to explain the technological innovation in this book. Did not know it as a child. I know it now. So now we're pivoting away from the book to the actual history of steam shovels as described by American genius Clay Christensen. That's exactly right. Okay. So steam shovels used to have a single steam engine that pulled cables. You may have seen the cables. You're in it! We're in steam shovels! So they pulled cables to make the giant claw pick up dirt. Okay. And then along came the gasoline shovels, the gas engine. But they used the same cables.

15:35They just installed a different engine. They had cables. Is this sustaining innovation? Yes. Am I tracking correctly? The children's book doesn't tell you this, but it was actually fine for the steam shovel companies. Bad for Marianne. Fine for the companies. 23 of the 25 largest steam shovel companies survived this innovation.

15:53Clayton M. Christensen:So they just switch over. Everybody switches over. Yeah. Yeah, and then everybody has a gas engine, but the same companies are on top. Now, the twist in the story, they don't get into it in the children's book. We should write that version, by the way. The disruptive one of Mike Mulligan? Yeah, absolutely. And that was hydraulic excavators in the late 1940s. Now, if you see an excavator today, you'll see there's little pistons at each of the joints. That's what makes the claw move. But this was a new technology. and this would turn out to be the disruptive one because the hydraulic technology kind of sucked like it was weaker or slower or what they were smaller you just couldn't run a giant marianne sized digger you had a tiny digger and the big earth moving companies they knew about this technology and they looked into it and they talked to their customers and their customers were like we're digging the big canals and the deep holes for the sellers of the tall skyscrapers.

16:57We need a really big steam or gasoline engine. This hydraulic thing would take forever.

17:04Clayton M. Christensen:And so the big companies who care about their customers. Yeah, they're doing what they're supposed to. They're close to the customer. They're listening to what the customers want. They're serving the customer. There is no market for this. And so there were a few companies, J.C. Bamford, Henry Company, they started to make hydraulic versions of this and they sold it to a different set of people like farmers, landscapers. Smaller, basically people doing smaller projects. Yeah, because if you think about it, if you had to dig an outhouse, you're not going to like bring in Marianne the Giant steam shovel.

17:37But this all of a sudden gave you a chance to, you know, move a little tree or bury a cable. And it was good enough for the job, right? But then the hydraulics got better. So this is the twist. Yes. And then eventually the new technology could move as much dirt as the old technology. And then people realized, oh, they're actually more reliable and they're safer because there's not a big cable going through it. And then suddenly those tiny companies making the hydraulic shovels were on top. They became the big companies. Everyone moved over to hydraulics and that's what you see to this day.

18:14Clayton M. Christensen:Here, Clay Christensen wrote about these companies. These companies did not fail because the technology wasn't available. They did not fail because they lacked information about hydraulics or how to use it. They did not fail because management was sleepy or arrogant. They failed because hydraulics didn't make sense until it was too late. I love that. You assume that management made a mistake. But in this case, the goal of a business is to serve its customers and you can't abandon them to try a new market that you don't even know if it exists. Like you would be fired. You know, I like this because it's more interesting in the world when everybody is kind of smart.

18:56Like, oh, dumb people make dumb decisions and they lose and smart people make smart decisions and they win. Isn't a very interesting theory of the world. But a theory of the world that takes into account sort of complex dynamics and what's going on at different institutions and looks at all these people, it's like everybody is acting rationally in their own context. But in some of these instances, acting rationally or what seems to be rationally leads you to to destroy your business. Give me a Clay Christensen quote. OK. Successful companies routinely give their customers more and better versions of what they the customers say they want.

19:32But products that do not appear to be useful today may squarely address their needs tomorrow.

19:39Clayton M. Christensen:Don't ask your customers what they want. They don't know is what he's saying here. And even if you could tell customers, you're wrong, you're going to want this in the future, there's another big force holding incumbent companies back, and that is money and investors.

23:21And we are back. Clay Christensen took all his research on disk drives and steam shovels, and he put them into book form in 1997. Was it a children's book? No. It was The Innovator's Dilemma. It sold over a million copies, as the sticker, I'm sure, said on the front of it. And it won all the big business book awards. And the timing was really perfect, 1997, because it came during the rise of the internet, the dot-com bubble, the dot-com crash, like all of a sudden it seemed like disruptive innovation was everywhere. It was picking up at fruit fly speed. Big companies were vulnerable. Everyone wanted to be the flashy new startup.

23:59After reading the book, Jeff Bezos of Amazon.com said,

24:03Clayton M. Christensen:if you want to give us this. Dot-com. My mother-in-law calls it Amazon.com. Jeff Bezos said, as a company, one of our greatest cultural strengths is accepting the fact that if you're going to invent, you're going to disrupt. A lot of entrenched interests are not going to like it. And can I just mention, I'm just going to do a little Jeff Bezos aside here, because there's this story of him when they created the Kindle. I'm a fan of the Kindle. He created this Kindle group and said to them, your job is to destroy our book business, right? Like he understood the implication and what it meant. I feel like at this point, if you're an entrepreneur writing any sort of press release, there's a little thing that pops up and says, do you want to use the word disrupt?

24:44You should use the word disrupt. There's a conference called disrupt. Literally called disrupt. Somebody should start a cheaper conference that everybody goes to instead. That's a little bit worse at the beginning. Now, that's a natural thing, but I'm more interested in the poor middle manager of a giant company. They're in an airport in 1999. They're looking through the innovator's dilemma. And if you read the whole book, you start to realize there is not a lot you can do to stop disruptive innovation, to stop Jeff Bezos. The thesis of the book is that big companies have such a strong incentive to keep doing what they're doing.

25:19And we talked about the pressure from customers to keep serving the same products, you know, maybe slightly better, right? But there's also pressure from investors. Jacob, if you're an investor in a company, which I know you are, what do you want it to do? You want it to make money. Exactly. That's the whole point.

25:37Clayton M. Christensen:If you give a dollar to a company, you want it to spend that dollar on the thing that makes the most profit. Yes. Profit maximizing. That is the term of art. And every business is resource constrained. So if you spend money on one thing, it means you're not spending it on another. And so you want the business to focus on the thing with the highest return. Clayton argued that disruptive technology isn't just worse than old technology. It usually has lower profit margins at first. Profit margins are a huge deal for businesses. And investors, serious investors, want those margins to go up. And they certainly don't want them to go down.

26:14Clayton M. Christensen:Clayton illustrates this profit margin incentive with a story about steel mills. Steel mills. Okay, that seems up your alley. Ah, I know. These are all 12-year-old boy examples. Have you been to a steel mill? Oh, of course I've been to a steel mill. Both abandoned and actual working steel mill. and the thing that's amazing about them is the integrated steel mills the big steel mills are huge acres and acres and acres and they got train tracks coming in for iron ore and coal and you know the buildings are enormous and there's lava looking stuff pouring out so amazing and it's also so expensive you know we're talking billions of dollars to to build the plant billion to operate it every year.

26:59This is the classic big business. Heavy industry. Yeah. The heaviest. So if you have a very expensive industry,

27:09Clayton M. Christensen:Jacob, if you're a salesman for the steel company, what do you want to do with your steel? I want to sell it for as much as I can. Yeah. So you look for the richest people you can sell steel to. So car companies who want gleaming steel for their cars. Planes. Planes, absolutely. GE turbine systems, industrial appliance makers. Like that is where you make your profit margin because it's so expensive to make steel. Now, you know, the disruptions coming here, but it's always surprising when it happens. Tell me the story. I do better than tell you the story. I found another children's book. So it features a unicorn on the front and a steel mill.

27:49So what's it called, Reverend? It's called A Recycling Adventure to the Steel Mill. Is that a real book? It is a real book. But this essentially tells the story of the disruptive innovator in the steel industry and of unicorns, too.

28:06Clayton M. Christensen:You're saying unicorn. You don't mean a billion-dollar startup. You mean a horse with a horn on its head. That's how you make it interesting, yes. Okay. Today, you'll see how scrap metal gets turned into brand-new steel using something called an electric arc furnace. And there's somebody else pointing at say, and they say, that's ferrous metal. It's magnetic because it contains iron. Yes, yes. Should we point out that there's a building that says Nucor on top? That seems quite important from what I know of this story. They are one of the disruptors, yes. And probably paid for this book. It has that look.

28:42Clayton M. Christensen:Okay, do I keep going? Yeah, one more page. First, we pick up the scrap metal with an electromagnet. Next, the metal is dropped into an electric arc furnace. Then comes the biggest fireworks display you've ever seen. Woo! So, Nucor, the company featured in the book, in the late 1960s... It actually says Nucor on the cover. I know. I don't think this book is on the up and up, Robert. So, before they got in the publishing industry, Nucor is the largest steel mill and children's bookmaker in the country, the combination. So, in the late 1960s, they opened what is called a mini mill, which is just a kind of a tiny steel plant.

29:22And instead of using coal to have a giant furnace,

29:26Clayton M. Christensen:they use electricity. And just to be clear, at this time, they're like a startup doing this? So no, they are a large company that's been around for a long time, but they have a division that's providing steel to another one of the divisions. Got it. So they designed this thing, this mini mill. It's about 10th the size of the big steel mill. Okay. And a 10th of the cost. They use the recycled steel. And they were a classic disruptor because they were cheaper, they were smaller, they required less labor, and they made kind of crappy steel. It was weaker steel, it was bumpy, it was ugly. Like, no car company is going to want mini-mill steel.

30:07But, Nucor and these other companies knew that there was a market that didn't care about shiny, nice-looking steel. And that was, get excited, rebar. Oh, I love rebar. Yeah, rebar is the stuff you put in concrete to make it tougher. That's like a breakthrough, right? Like when you're building a building, the rebar-concrete combo is like a huge innovation of its own. Yeah. When you go to the developing world, for whatever reason, it's like ubiquitous, right? The building where there's like, they built two stories, and you can tell they're planning on building a third because there's the rebar sticking out the top.

30:43And, you know, if you want the rebar, you don't really care what it looks like.

30:47Clayton M. Christensen:You just want the cheapest rebar. You're not going to see it. Now, this is key. The big steel mills, they had been making rebar, but it was such a low profit margin. It was like 7 % profit margin, much lower than selling steel to GE. So when Newcor and these small mini mills came around, the big companies were like, thank God. We don't have to be in this dog-eat-dog commodity business anymore. And getting out of that business presumably would mean their margins go up, which is what they want, right? You get out of the low margin business, your overall margin is going to go up. This is exactly right.

31:23And the big steel mills, they were suffering from, you know, foreign competition in the 70s and the 80s. And they really needed this high profit steel to look good to investors. And for a while it worked. It worked great. Until, until, of course, new corn, the mini mills, they get better. They get better at making steel and they expand into angle iron. Oh, that's fine. I don't know what it is either. It's like iron and angle and bars. They make corrugated steel, you know, for Quonset huts, you know. But they're moving up the quality ladder here.

31:58Clayton M. Christensen:The Quonset hut business, look out. And eventually they make the massive structural beams that are good enough. And then they make rolled up steel, which is the nice fancy steel. And Nucor has vacuumed up the customers from the bottom up. And the next thing you know, Nucor, hero of our children's book, is the biggest steel company in the United States. Classic Checkmate. People in business love these stories. I kind of felt it as I was reading Clay Christensen's books. It's like a horror film for executives. And the key to a horror film is you see the evil thing coming. You know it's coming somewhere.

32:41You just don't know when they're going to jump out at you with a knife. I mean, also maybe, I don't want to go too far here, but it's a little like a classical tragedy, right? Like the Greek tragedy, where like there's this tragic flaw, right? The need to be a profit maximizer, the need to listen to your customers. And that is the sort of inevitable undoing of the incumbent, of the hero.

33:04Clayton M. Christensen:So I imagine the executives of these companies, they read the innovator's dilemma and they're terrified. They're properly scared. And remember, Clayton M. Christensen is a Harvard Business School professor, so he knows what to do next. He's going to sell the antidote to this poison. In 2003, he publishes The Innovator's Solution. Come on. In 2009, he publishes The Innovator's Prescription. No! In 2011— They can stop! This is the horror movie! In 2011, he put out The Innovator's DNA. No, he didn't. He did. I'm a little disappointed in Clay Christensen, Eagle Scout. Oh, he had to make the money.

33:47There wasn't to that. No, it's totally fair. Serving the customers. Chicken soup for the CEO's soul. They love business books. So the good news for corporations, there is a way to fight off the disruption. The bad news is you have to start to act like a disruptor. After the break.

36:40We are back. Clayton M. Christensen did pretty well for himself. After the success of his many innovators' books, he started his own consulting firm, but he stayed a professor at Harvard for 28 years, writing case study after case study on failing companies. He was a Mormon, and he moved up the ranks of leadership roles in the church. And near the end of his life, he started to write more books about personal meaning and finding your way in relationships. And just like in The Innovator's Dilemma, happiness, he says, is a matter of resource allocation. Why don't you give a little life lesson from Clayton?

37:18The secret to happiness is having strong, loving relationships and intentionally investing time in them. Seems reasonable.

37:26Clayton M. Christensen:We're now a happiness podcast. I mean, I'm not out on that. I basically agree with that. Yeah. No, it's good. It's so simple. But in terms of fixing your company, well, Clayton had sort of a more complicated prescription. He basically said there are three solutions for a big company facing disruptive innovation. Number one. A list. Wait it out. Wait it out. When the new technology is mature enough and profitable enough, then you have all the money and you can just move into the industry and blow away the little guys. Okay, right. So you see the disruption coming, but when it's still really cheap and crappy, you don't get involved.

38:06You wait till the new technology, the disruptive innovation is big enough, and then you move in.

38:11Clayton M. Christensen:Rarely works, he says. Rarely works because at that point, the disruptors are better at doing the thing. Aha, right. It's their whole business. They've been learning it. Yeah, and they have different techniques, and they're smaller, and they're more nimble, all of this sort of stuff. But it does happen occasionally. I think about Apple. It used to be Apple computers, right? It's hard to think about anything that Apple was first to. There were smartphones before the iPhone, but they were kludgy, low bandwidth, low profit. Exactly who you expect to be the disruptor. Was the BlackBerry those things?

38:45Clayton M. Christensen:It was a BlackBerry. It had a little thing. It was definitely, I mean, I mean. I remember the low bandwidth. I mean, I tried to navigate on a little map on my BlackBerry. And it was super hard. It was basically for email. It was basically good for email. Yeah. Apple moved in with the iPhone at just the perfect time, just as mobile internet was getting better, getting faster. And, you know, it made the phone beautiful and intuitive. So it pulled this off, but it's very hard to do. So Clayton has solution number two. Buy your competitors. That's the one they're all doing now, right? That's what all the big tech incumbents are doing.

39:21They're buying everybody. Yeah. And, you know, old steel and steam shovel companies probably didn't have a billion dollars laying around. Like literally laying around. Literally laying around to buy their competitors. But the internet economy companies do. and founders these days have such control that I think that they don't care as much about their investors and about maybe even their customers. Like they are more willing and have more control of their company and they've read The Innovator's Dilemma. Well, right, they've internalized it, right? They understand, like it is more fruit fly-like now, right?

39:58We are not in that 1995 era where the biggest companies in the world have been around for a hundred years. The biggest companies in the world now are largely run by the people who found them who were themselves disruptors. So they are built to be afraid of being disrupted.

40:12Clayton M. Christensen:Yeah, Facebook, right? Huge disruptor. But by 2012, Facebook is the big social media company. Their investors were thrilled. Their customers were thrilled. Everybody loved the Facebook, right? But inside the company, Mark Zuckerberg was noticing more people using mobile phones. And he knew that Facebook was big on the desktop computer, that maybe the demographics were getting a little bit older than he liked. And he notices a company called Instagram. Zero revenue, 13 employees, 30 million users. So very good. But Facebook had a billion users. And Mark Zuckerberg, you know, I'm sure he read The Innovator's Dilemma.

40:52And he did something that seemed sort of insane at the time, which was he bought Instagram for a billion dollars. Like a billion dollars. Zero revenue. 13 employees. Took them three or four years to get ads on there, right?

41:06Clayton M. Christensen:But the disruption was averted, you know, at least for Facebook. Yes, and then they did it again with WhatsApp a few years later, right? Exactly, when they saw that internationally they needed something that people could message on. And, you know, Google bought Android, Apple bought Siri, Salesforce bought Slack. Good luck to them. But it doesn't always work. You know, Yahoo bought Tumblr. Don't know which one's in worse shape now. Okay, so first two ways to avoid disruption, have the timing genius of Steve Jobs or the spare cash, Mark Zuckerberg. And then there's the third way, which I find really interesting, create a small disruptor within your company.

41:47Clayton M. Christensen:Culturally, that one is super interesting. Yeah, and hard to do because you can't fake it. You can't just put a conference room aside and say, you're the disruptors. Because what it really means is if it works, the disruptors should put most of your company sort of out of business, right? As a company, it'll still work. But the people who've been spending their lives selling the incumbent thing aren't going to like the disruptor. They're going to think it's bad. So the companies that have succeeded at this, Hewlett Packard, HP, maker of printers and many other things, they had in the 1980s this amazing new product called the laser printer.

42:27Shoots out printed copies of things. I don't know why I'm explaining what a printer is.

42:33Clayton M. Christensen:I'm so used to explaining. Wait a minute. You're saying. You're saying you type something. I've created a white piece of paper. And it comes out not white with symbols on it. I know. I know. So Hewlett-Packard is number one in laser printers, and there's this new technology called inkjet printers. It's a smaller printer. It has these little buckets of ink in there, and it's kind of blurry and doesn't work that well. It's slower. HP, Hewlett-Packard, sees that this could disrupt their big laser printer business. And so what they do is their printer division's in Boise, Idaho. They send a bunch of people to Vancouver, Washington, whole new office, give them their own budget, their own decision-making power, and essentially say, put us out of business.

43:18Like, do the best inkjet printing you can. And this is the essential thing.

43:23Clayton M. Christensen:You don't have to be as profitable as the rest of the company. Right. The margin. They are solving the margin problem. You just need to make enough money to make more inkjet printers and come up with a solution. And eventually the HP inkjet printer becomes big because everyone wants a small, cheaper thing that they could put next to their laptop computers. It's cheaper until you have to buy more ink. That's the other thing is once they figured out that you could make the printer that only accepts HP ink, then you could sell them ink forever. If you think about it, that one seems really hard to do because the fundamental thing they're doing is agreeing to lower their margins, right?

43:57To whatever extent they're putting capital into this little inkjet division, they're accepting that their overall margins are going to come down, which is antithetical to what executives want to do. That's why that one seems hard. Very hard. And few people do it. But if you can pull it off, then you get to be the disruptor and the incumbent company at the same time. Woo! It didn't cost you a billion dollars.

44:23Clayton M. Christensen:Jacob, it's time for the To Be Fair section. To be fair, none of this is true. It's true in a business school sort of way, which is it is a smart and a useful theory that you see everywhere these days, but it's not a law of nature. And I think Clayton admits to this too, that he picks companies to profile that fit his thesis. There's lots of companies that don't work this way. Like lots of times the big company is fine. The disruptors all fail. Pushkin's own, very own Jill Lepore used to host a show called The Last Archive. About a decade ago, she was writing for The New Yorker. She pointed out that Clayton often doesn't include complicating factors.

45:08For instance, she pointed out the fact that the big steel industry had unionized labor and a lot of the mini mills did not. So it is easier for them to be nimble and profitable if they don't have to deal with legacy union contracts. She also pointed out that Clayton started an investment firm to invest in disruptors. He had this big idea, why not make money off of it? And it ended up losing money and he shut it down. Because like predictions harder than describing the past. But despite all this, like, I think it's fair to pick Clayton as our third American genius because his ideas are so core to how we think about business today.

45:53Even just psychologically, everyone wants to be a disruptor. You know, even the largest companies on earth call themselves disruptors. And you can't launch a business without putting out a press release saying you're disrupting something, right? So Casper Mattresses said it was disrupting the sleep industry. Which it kind of was. It kind of was. Yeah. I'm sure the people selling mattresses at the time said, those mattresses are terrible. Like, I don't even know, but I'm sure that it happened. That's what you say. You can't even lay on them before they ship it to your house. Yeah, who's going to want that?

46:25Rubicon, the Uber of trash. What? Says they're disrupting waste management. Uber for trash? The founder of Nature Commode. Toilet company? A composting porta potty says, this is a quote, we're looking to disrupt an industry that is ripe for disruption.

46:45Clayton M. Christensen:Well, that's the place to disrupt. Two disruptions in one sentence. Ripe is a good word in the toilet business. And I've been most fascinated by what we've seen over the past two years in the AI world. The largest corporations, literally the largest corporations in the world, are panicking and trying to disrupt themselves by spending billions, it totals trillions when we look at all the companies, to innovate in the business that they're in. So I think before Clayton Christensen, Microsoft might have thought, or Microsoft, like we're an invincible software company. Why do we need to be an AI company?

47:23Same with Meta, X, Google. They're the top of their businesses. Why spend this enormous amount of money on AI? Because I think they now feel this panic that the innovator's dilemma put in every business person's soul. You don't read the book and say like, yeah, it was a good run being an incumbent company. You look at it and say, I want to do that. Yeah. I want to not die. I want to not die. Yeah. And now if someone were to tell you that there's a chance that Anthropic, an AI company with 4 ,000 people, could unseat the largest corporations in the world, we're like, yeah, that could totally happen.

48:04We don't question it at all anymore. And this is the power of the idea that Clayton unleashed. It's terrifying. It's motivating. And no one wants to be the case study in whatever the next sequel is. The innovator strikes back. The last innovator. The last innovator. Like, you should write that.

From the publisher

Why have so many tiny start-ups come from nowhere to take down huge established corporations? Is it because the incumbents were dumb? Harvard Business School professor Clayton M Christensen decided to explore these David versus Goliath battles - and came up with a theory to explain why seemingly solid businesses suddenly lose market share... disruptive innovation.  

In his hit book, The Innovator's Dilemma, Christensen explored how flawed products from small companies can suddenly catch on, disrupt the market and steal customers from established corporations. Christensen - a life-long Boy Scout - was an odd champion for "disruptive innovation", but his ideas have totally changed the business landscape.
