In 1980, nobody wanted a personal computer. The machines were toys. They had tiny screens, limited memory, and processing power that could not touch the mainframes and minicomputers running the world's serious work. The customers who mattered, corporate IT departments and large organizations, had no use for them. The companies that made real computers, Digital Equipment Corporation, Wang, Data General, all looked at PCs and saw irrelevant gadgets for hobbyists.
**Author:** Clayton M. Christensen **Estimated Reading Time:** 42 minutes
### What You'll Learn
Why great companies fail despite doing everything right. The hidden patterns that cause industry leaders to lose their markets to scrappy newcomers. How to spot disruptions before they destroy your business. The organizational forces that make innovation so difficult inside successful companies. Practical frameworks for building new growth businesses without killing your core operations.
### Who This Book Is For
Leaders who sense their industry is changing but cannot articulate how. Entrepreneurs building products the incumbents ignore. Managers frustrated by their organization's inability to pursue exciting new ideas. Investors trying to separate genuine disruption from hype. Anyone who has watched a dominant company collapse and wondered how smart people failed to see it coming.
In 1980, nobody wanted a personal computer. The machines were toys. They had tiny screens, limited memory, and processing power that could not touch the mainframes and minicomputers running the world's serious work. The customers who mattered, corporate IT departments and large organizations, had no use for them. The companies that made real computers, Digital Equipment Corporation, Wang, Data General, all looked at PCs and saw irrelevant gadgets for hobbyists. By 1995, Digital Equipment Corporation was gone. Wang was gone. The entire minicomputer industry had been obliterated. The hobbyist toy had eaten their world. This pattern repeats across industries with astonishing regularity. Steel mills dismissed mini-mills as incapable of producing quality steel. Department stores laughed at discount retailers selling cheap goods in warehouse spaces. Blockbuster watched Netflix mail DVDs in red envelopes and saw no threat to their thousands of profitable stores. In every case, the established leaders were not stupid. They were not lazy. They were doing exactly what good managers are supposed to do: listening to their best customers, investing in profitable products, and pursuing high-margin opportunities. That is the puzzle at the heart of this book. How can doing the right thing lead to failure? How can excellent management, the kind taught at every business school and practiced at every successful company, become a liability? Clayton Christensen spent years studying this phenomenon. He examined the disk drive industry, where new companies seemed to emerge from nowhere and topple established leaders with alarming speed. He looked at mechanical excavators, where a new technology displaced an old one despite being initially inferior on every metric that customers cared about. He studied retail, steel, computers, and motorcycles. In every case, the pattern held. The answer he found is both simple and deeply counterintuitive. There are two fundamentally different types of innovation. Sustaining innovations make good products better. They serve existing customers by improving performance along the dimensions those customers already value. Established companies…
