Bloomberg: As a slew of companies, from Dish Network’s Sling TV to Sony, begin to offer online television viewing, U.S. cable providers may be forced to respond with their own nationwide live streaming packages, or lose even more subscribers, according to Rich Greenfield, an analyst at BTIG in New York. The result will be “nationwide war” as cable companies battle each other and the newcomers for online subscribers, said Greenfield. Regardless of where they live, customers could choose from among such providers as Comcast, Charter and Cox.
