Cablevision offers HBO on TV. Now it's promoting the online service for its Internet customers

Cablevision is offering the new HBO Now online service to its Internet customers, even though the service could persuade more people to drop their cable TV packages.

The company, which has customers in the New York City area, said Monday that Cablevision customers can sign up for HBO Now through Cablevision. That means they can pay for it on one Cablevision bill.

HBO has said the service will launch in April in time for the new season of "Game of Thrones" for people who have iPads, iPhones and Apple TVs. It costs $15 a month — the same as what Cablevision charges for HBO on TV.

Cablevision, which is based in Bethpage, New York, says it will provide pricing details later. Terms of its deal with HBO were not disclosed.
