Dive Brief: 

• Facebook announced it will now be offering video ads for its mobile app. 
• The social networking giant is also adding the option to bid on ads on a cost-per-action (like installs) basis rather than clicks or impressions. 
• A Facebook spokesperson said all ad sales, including video, would continue to be sold by auction, which should keep the prices competitive.

Dive Insight: 

Facebook continues to move forward offering a wider variety of ad options. In a mobile app environment, video makes sense for many advertisers like games and other apps. According to Facebook, 70% of users access the social network through a mobile device, so advertisers will likely be jumping at the chance for another way to reach those users.
