Premium cable network newcomer Epix is working to continue bolstering the direct distribution portion of its business today, as it has announced that it will be releasing streaming apps for the PlayStation 3 and PS Vita. The new apps are launching later this quarter and in the spring, respectively, and they join a rather full roster of applications (iPhone, Android, Xbox 360, Roku, and even BlackBerry PlayBook apps are already available) that bring Epix's movie and entertainment event catalog directly to subscribers. The move is the latest step by Epix and the three movie studios — Paramount, MGM, and Lionsgate — that own it to maintain power over the distribution of their content. We're sure Epix also hopes that its plethora of apps will convince cable customers to pay up for access to the premium network, which stands in last place compared to competitors like HBO, Showtime, and Starz, but the network's movies are also available sans-subscription on Netflix and Amazon Instant Video.
