Chris Vanderhook

COO, MySpace

Chris Vanderhook, the COO of Myspace, relaunched music-focused social site along with his brother, Tim, and Justin Timberlake. Once the top social media network--and for a brief moment in 2006, the most-visited site on the entire web--Myspace suffered a notorious fall from grace with the advent of Facebook. Tens of millions of users switched sites, fleeing a clunky, ad-choked, sketchy-profile-infested ghetto. Myspace's revamped mobile app allows anyone to create and share their own online radio station for free.
