Facebook last night announced a deal to buy online video advertising technology company LiveRail.
The companies did not disclose how much Facebook is paying for seven-year-old LiveRail.
LiveRail's customers includes ABC, Dailymotion, A&E Networks, and Major League Baseball website MLB.com.
San Francisco-based LiveRail touts itself as the world's largest programmatic platform for effectively targeting video ads to online viewers.
The company has 170 employees and delivers more than seven billion video ads each month for hundreds of customers.
"Our goal at LiveRail has been to build the best technology in the world to help connect the digital video advertising ecosystem," the company said in an online post.
