Comcast to Start 'Streampix' Video Service Comcast said on Tuesday that it would start a new video streaming service, its latest effort to keep subscribers happy despite an onslaught of new viewing options. Called Streampix, the service will give Comcast's 22.3 million Xfinity cable subscribers access to 75,000 television shows and movies via cellphones, tablets and laptops. The service is the result of a handful of licensing agreements Comcast has struck with media companies like Disney, Sony Pictures, Warner Brothers and its own NBCUniversal. As the nation's largest cable company, Comcast has aggressively led efforts to deliver content on multiple platforms via a subscription model. The effort, known as TVEverywhere, is aimed at keeping customers from canceling the monthly cable bill. Comcast lost 17,000 video customers in the quarter that ended Dec. 31, compared with 135,000 in the same period in 2010. "The main reason we're launching this product is we feel it helps provide value in our subscription service," Marcien Jenckes, Comcast's senior vice president and general manager of video services, said in an interview. Last month, Comcast struck a 10-year deal with Disney that will allow subscribers to watch television shows, movies and sports inside and outside the home. The market for online video-on-demand services like Streampix is increasingly crowded. Earlier this month Verizon said it would team up with Redbox to introduce a Netflix competitor. Amazon has its Prime service, and Wal-Mart's Vudu streaming service comes installed on most new television sets. Mr. Jenckes said Comcast was not interested in competing with Netflix or offering the service to nonsubscribers. "We're interested in strengthening our business in the multichannel subscription service," he said. Beginning Thursday, Streampix will be available to Xfinity subscribers for $4.99 a month, or as part of some higher-end cable packages. Netflix's streaming service starts at $7.99 monthly. In addition to current video-on-demand content, Steampix will give Xfinity customers access to complete past seasons of television series like"30 Rock," "Lost" or "Grey's Anatomy" and movies like "When Harry Met Sally" and "The Big Lebowski." On Tuesday, Netflx said it stuck a deal to have exclusive access to the Weinstein Co."s foreign language movies and documentaries, among other films. That includes the Oscar-nominated mostly silent film "The Artist." Netflix's stock fell 2.27 percent after the Comcast announcement, to $119.35, compared with a 52-week high of $304.79. Comcast was trading at $29.07 on Tuesday afternoon, compared to a 52-week high of $29.27.
