Variety: For the first time, HBO is offering free access to full episodes of its original programming on Facebook, a move that shows the growing clout in the video space of the social-media giant. The premiere episodes of “Ballers” and “The Brink,” the premium cable network’s newest comedy series, will be available on Facebook for a limited time, after their June 21 TV debuts. According to HBO, the episodes will not be available on YouTube or any other third-party digital platform.
