"There's a lot of demand from some of our top video game networks," Kamangar told Reuters. "They have such big audiences that they can start to segment their audiences into those that are willing to pay a higher amount."

YouTube was founded by former PayPal employees Chad Hurley, Steve Chen and Jawed Karim in February 2005, and has been under Google ownership since November 2006.
The site boasts more than 800 million worldwide users, who watch a combined total of more than 3 billion hours of video each month.
