CBS News: It was Susan Wojcicki who pushed for Google’s nearly $2 billion purchase of YouTube in 2006, before most of the world knew what online video was. Since then, YouTube has been valued at up to $40 billion. Yet one big question remains: Does it make a profit? “Right now, we’re investing in YouTube,” Wojcicki said. “I think we’re still pretty early in the online video market … and so really, our focus has been in investing in it as opposed to making a profit right now.”
