THR's 2012 Digital Power 50

Harnessing dual passions for technology -- he started a computer games software business when he was 14 -- and movies, Needham co-founded the Internet Movie Database in 1990 and sold it to Amazon in 1998 for an undisclosed mix of cash and stock. IMDb, the go-to site for information on movies, TV and actors, lists 2 million entertainment titles, attracts 110 million unique visitors globally each month and has a paid-subscriber level. Its mobile app has been downloaded 30 million times. Needham, 44, also oversees the Internet's top box-office reporting site, BoxOfficeMojo, which IMDb purchased in 2008.
