Innovator's Dilemma is definitely the best - it was based on his PhD, it is brilliantly and simply written, and is also supported by actual data. The above terminology is from the 3rd book, after Innovator's Solution, called "Seeing What's Next". Although he's refined and modified his theories with experience in applying them to many real situations, the book is no where near as well written, even includes a constant stream of ridiculous puns (in the aviation chapter), often uses casual language - and doesn't provide any actual data. Also, the second two books are only co-authored by Christensen (who is a Rhodes Scholar btw). That said, something like this may be a better resource: http://en.wikipedia.org/wiki/Disruptive_technology http://en.wikipedia.org/wiki/Disruptive_technology and it's all over the web in general, so googling works. You may also like Moore's "Crossing the Chasm" - the same ideas independently developed at the same time, but a how-to guide, rather than an academic description. He was a marketing guy, who noticed these patterns in how Apple etc succeeded. Andy Grove (for example) agreed with him. This is also a beautifully written book (guy's a PhD of English Lit).
