Google said today that Susan Wojcicki, an early employee who has been serving as a senior vice president overseeing advertising and commerce, will now run YouTube. Salar Kamangar, who has run the video service since 2010, will stay at Google working on unspecified early-stage projects, according to Re/code. As Re/code noted earlier, the move puts a prominent advertising executive at YouTube in the wake of publishers on the service complaining about the difficulties they have making profits on the site. In a statement sent to The Verge, Google CEO Larry Page was vague on what the change might mean for YouTube.
