Clayton Christensen called this The Innovator's Dilemma in a book published in 1997. It's why Netscape was able to undermine Microsoft when the web came out. Microsoft had a huge beast they had to move, Windows, and all its apps, and while they had a hardcore, scrappy and rich culture, they couldn't overcome the inertia that comes from being dug in, with their cannons pointed at the already-vanquished IBM, not the upstarts that came from the VCs in Silicon Valley. #
