Probably. I think Airtime originally came about just from seeing Chatroulette's initial wild success and traction. He and Fanning saw an opportunity to do it better. Then that idea got some validation as Chatroulette filled up with pervs and imploded. Which is the big problem Airtime solves.

But beside that, it's a pretty obvious next step for the world's largest social network and I'm sure he saw that early on. As did Google with hangouts.
