Facebook has agreed to acquire LiveRail, an advertising technology company that helps companies like Major League Baseball (MLB.com) and Dailymotion serve ads in the videos that appear on their websites and apps. LiveRail was founded in 2007 and offers a platform for online video publishers that help them find and serve better ads possible. LiveRail also helps marketers by providing them with access to video inventory and the information that they need in order to decide where to show their ads.

With LiveRail, Facebook will make video ads better and more relevant for the millions of people who watch digital video every month. More relevant ads will be more interesting and engaging to people watching online video, and more effective for marketers too. P

"We believe that LiveRail?s excellent product - known in the industry as a video supply-side platform or SSP - and Facebook's expertise with relevancy, delivery and measurement will help us make video advertising much better for everyone," said Brian Boland, Vice President of Ads Product Marketing and Atlas, Facebook.

In March, Facebook began offering 15-second video ads from a limited number of companies on its website.
