MySpace founders Tom Anderson (L) and Chris DeWolfe.
AGE: 41 and 37, respectively
OCCUPATION: Founders (CEO and president, respectively) of MySpace.com
NUMBER OF TIME COVERS: 0
PREVIOUS APPEARANCES ON THE TIME 100: 2
PRO: With over 100 million active users dropping little breadcrumbs of ad info (and Google pledging a $900 million ad deal), MySpace has more than paid for itself: the $600 million Rupert Murdoch shelled out for it looks like pocket change.
CON: But MySpace has acquired a rep as a site for teens — has its mantle of 18-to-49 Web dominance passed to Facebook? Tom's also been accused of lying about his age. (He's said he started the site at age 27, which would make him only 32 today.) Finally, Tom is everybody's "friend" on MySpace. Does that mean he's really nobody's friend?
