> How many companies have been "the unstoppable juggernaut" for 50+ years? AT&T isn't the AT&T from 30 years ago. [...] Microsoft was the unstoppable juggernaut... and then Apple and Google came along. These are very good examples. However in both cases the decisive action was taken by federal antitrust enforcement. The Bell System was broken up by a consent decree [1] and Microsoft only dropped its aggressive Browser Wars tactics (e.g. giving IE special API access) after a major antitrust case [2]. It makes for a nice story, but in practice big companies are rarely (if ever) defeated by scrappy competitors / market forces.
