Is Facebook really eating into YouTube's territory? The latter doesn't think so.
YouTube has downplayed the threat of Facebook displacing its dominance of online video, saying both companies will be able to grow rapidly for years by cannibalising the television advertising market.
Robert Kyncl, head of content and business operations at YouTube, was quoted as saying by the Financial Times that the online video market was expanding so fast that "it will be a decade before we bump into each other".
He said Facebook's and other players' arrival shows that online video is "becoming mainstream", but it would not derail the YouTube juggernaut.
Facebook, which has 1.4 billion monthly active users, has been putting video ads into users' feeds for more than a year.
Recently, it muscled further into YouTube's territory with a trial to share advertising revenue with video creators who publish on the social network.
Facebook will match the revenue split offered by YouTube, giving content creators 55 percent of the proceeds of ads that run next to their videos.
