Last year I read The Unincorporated Man, about a man from the past who's woken up in a future where people have become corporations, with their stocks bought and sold by others. Their shareholders determine their lives, from what job they'll get to when they can take a vacation.
Apparently there's a real life Incorporated Man, and his name is Kenneth Michael Merrill. You can read about him at Wired. It's an interesting - and potentially terrifying - article. Merrill incorporated in 2008 and has already given his investors the chance to decide what projects he works on and who he's allowed to date.
