When you want to say that a company is small-time, you can say they're "a Mickey Mouse operation". I'm not entirely sure when that saying started, but it makes absolutely no sense any more. Mickey represents one of the biggest media and entertainment companies in the world. They own four amusement parks and enough lawyers and lobbyists to change United States copyright law as if it exists only for them. They have revenue of billions a year - after tax. They could probably buy an entire state and set it up as their own sovereign country. A Mickey Mouse Operation should conjure up images of world-eating corporate machines, not two guys in a shed.

PPS - Not my generation, anyway.
