In a first for HBO, the premium cable network is promoting its new original series “Ballers” and “The Brink” by offering free access to select full episodes on Facebook. The premiere episodes, to remain on the social platform for a limited time, became available yesterday, three days after their debuts. “According to HBO, the episodes will not be available on YouTube or any other third-party digital platform, nor will they be available on cable, satellite or telco TV services (except to HBO subs),” reports Variety. “In addition to Facebook, the episodes are also available on HBO Now — its recently introduced over-the-top service — and HBO Go, for pay-TV customers.”
