Question: is there a canonical list (or a good set of lists) on what are considered to be disruptive innovations?

As I recall, Christensen's initial set were hydraulic earth-moving equipment (vs. steam shovels), disk drives, and ... I forget exactly. Possibly the Japanese auto industry starting from small engines (motorcycles, etc.), then cars (Honda). Possibly PCs, disrupting minis and mainframes?

My copy of the book seems to have gone walkabout.
