Variety: Watch out, YouTube: Facebook wants to eat your lunch — and one of its execs just said that the social network will mostly consist of video posts in the very near future. “A year or two from now, we think Facebook will be mostly video,” said Facebook’s head of ad product Ted Zagat during a panel at Variety’s Entertainment and Technology Summit in Los Angeles. Zagat added virtual reality could be the next big shift after that, with Facebook investing heavily in the space.
