Comcast is set to launch a new streaming cable TV service called "Stream," which users could access through smartphones, tablets and computers.

"Stream will be available to our Xfinity Internet customers for only $15 per month and will first beta testing launch in Boston at the end of the summer," said Matthew Strauss, Executive Vice President and General Manager, Video Services for Comcast Cable in TV. He added that after Boston, it would be made available in Chicago and Seattle, while the rest of the of the U.S. will be served early in 2016, according to New York Daily News.

The new service from Comcast would mean an additional monthly cost on top of their usual internet bill. Nonetheless, Stream would allow them to watch shows from about a dozen channels on their smartphones, tablets and computers. Fox, HBO and NBC will be some of the channels available for the new Comcast service, the publication added.

Stream users will also have access to movies on-demand and a cloud DVR that lets users record and stream shows from their devices.

Strauss noted that the target market for cable TV had changed because not everyone wants a full pay-TV bundle and some prefers to watch TV outside of their homes which typically requires an additional cable subscription.

Stream would be in direct competition to Sling TV, but it has several differences, according NBC News. Sling TV, which allows access to ESPN channels as part of its $25 core package, charges an additional $15 a month for HBO. Stream, on the other hand, would offer HBO at no additional cost.
