Facebook will shut down LiveRail, its video advertising trading platform, which connects videos to ads through an automated bidding system, acting as a matchmaker between publishers and advertisers.

LiveRail was acquired by Facebook in July 2014 for between $400 million and $500 million. Facebook's goal is to optimize the video advertising experience, but the end result doesn't seem to be as good as expected.

Facebook advertising executive Brian B. Berland acknowledged in April that integrating LiveRail's technology took longer than they expected, and that advertising fraud and visibility issues had changed the direction of the project.

Facebook has laid off dozens of LiveRail employees in the past few months after the company's chief executive left the company. However, Facebook will not give up the LiveRail brand, according to people familiar with the matter.

In addition, Facebook confirmed on Wednesday that it would close FBX, an advertising trading platform that allows third-party advertising companies to buy desktop Facebook ads. The successive closures of these ad trading platforms seem to signal that Facebook will devote more energy and resources to its self-developed advertising platform, the Facebook Audience Network.
