From a report: Facebook's push toward original video content will take a big step forward Thursday with the launch of a new section, dubbed Watch. The new tab, which Facebook FB, said late Wednesday will launch for a limited number of U.S. users for now, will feature about 40 original series, with plans to eventually scale up to hundreds of shows. Facebook said it will become available to more users in the coming weeks. The Mountain View, Calif., social network is hoping to tap into lucrative TV advertising revenue to boost its ever-expanding bottom line. If successful, Watch could stem the ad-load slowdown for the rest of the year that Chief Financial Officer David Wehner warned about last month when Facebook filed its quarterly earnings. Facebook also hopes the Watch tab will open up a new method of advertising that doesn't clutter users' News Feeds, and keep its 2 billion users on its site longer. Company's founder Mark Zuckerberg is understandably very excited about the move. He says the company believes "it's possible to rethink a lot of experiences through the lens of building community -- including watching video. Watching a show doesn't have to be passive. It can be a chance to share an experience and bring people together who care about the same things." If that pitch sounds familiar to you, it's because TV has been doing it for more than 75 years.
