SHOWTIME ALSO COMING TO PLAYSTATION(R) VUE CLOUD TV SERVICE

NEW YORK - June 8, 2015 - On the heels of announcing the SHOWTIME stand-alone streaming service, Showtime has partnered with Roku, Inc.'s Roku(R) players and Roku TV(TM) models and Sony Network Entertainment International LLC's PlayStation(R) Vue for the launch in early July. SHOWTIME is a brand which has been embraced by consumers as the home for cutting edge original programming, sports and movies, and it is the only premium streaming service to offer customers live East and West Coast feeds. SHOWTIME will be available through these new internet distributors on all supported streaming platforms prior to the highly-anticipated July 12th season premieres of the critically-acclaimed hit series RAY DONOVAN, starring Liev Schreiber, and MASTERS OF SEX, starring Michael Sheen and Lizzy Caplan. The announcement was made today by Matthew C. Blank, Chairman and CEO, Showtime Networks Inc.

"We are thrilled that Roku and Sony have come on board for our launch in early July," said Blank. "Both platforms have distinct and loyal audiences and together they will build on our service and greatly expand the number of homes that will have access to the SHOWTIME service over the internet. This is fundamental to Showtime's strategy of putting the choice in the hands of the consumers regarding how, when and on what unique devices they watch our programming."

"Showtime has been a great partner over the years and Roku's inclusion as an initial launch platform for the SHOWTIME streaming service speaks volumes to our shared commitment to offer consumers the best entertainment experience available," said Steve Shannon, general manager of Content and Services at Roku. "Today more than ever, consumers want choice in how they access entertainment to view what they want, when they want it. The addition of SHOWTIME to the Roku platform helps provide that choice for millions of Roku customers and delivers TV on their terms."

"We're thrilled to launch SHOWTIME within PlayStation Vue," said Dwayne Benefield, Vice President, Head of PlayStation Vue at Sony Network Entertainment International. "We can't think of a better partner with whom we can begin to extend our revolutionary television experience to a nationwide audience."

Roku's customer base will be able to subscribe to SHOWTIME by going to the SHOWTIME app within the Roku Channel store on Roku players and Roku TV(TM) models anywhere in the U.S., for one monthly price ($10.99). Roku customers who sign up in July will be offered a 30-day free trial subscription to SHOWTIME. Roku customers simply need to go to the SHOWTIME app on their Roku device to sign up and create a SHOWTIME account. Subscribers can use their SHOWTIME account to watch the service across all SHOWTIME stand-alone service supported devices as well as online at www.showtime.com.
