Some of these were already revolutions. For example, i was in a large enterprise organization when Java came out. The programmers there were using Cobol, cics, Powerbuilder, maybe a little Eclipse, some Lotus Notes. The excitement of the programmers was palpable. They held impromptu meetings, made plans. Lots of excitement. Management wasn't so keen, however.

Smalltalk was a revolution as well. It was the first visible OO push. It even made Business Week with some of the technologies.

So some of these peak then fade.
