Comcast to launch streaming video service as it competes in an increasingly cordless industry

Comcast is launching a streaming video service as it faces growing intrusions from companies like Netflix and a rising number of customers who are becoming more mobile, using tablets and phones for entertainment.

The nation's largest cable company said the new service, called Stream, will cost $15 a month. Internet customers would be able to watch live TV from about a dozen networks, including HBO, on phones, tablets and laptops. The service includes on-demand movies and shows.

Comcast Corp. said Monday that it will launch the service in Boston at the end of the summer and plans to make it available to all its customers by early 2016.
