Microsoft from 1992 onwards? I guess we did; 20x increase in adjusted share price; in OSes alone, the release of Windows 3.1 (IMO the breakthrough move to GUI on PC, away from DOS), NT 3.1 (the original seed that grew to NT 3.51, NT 4, Win2K and all current kernels), breakthrough success of Windows 95. Looks like it worked pretty well, and made a lot of people very wealthy.
