Cable operator Cablevision Systems Corp said it would offer Hulu’s subscription video-streaming service to customers under its Optimum plans. The deal makes Cablevision the first cable or satellite provider to agree to distribute Hulu’s catalog of on-demand content, the company said on Tuesday. Cablevision has been losing cable customers to internet services such as Netflix and Hulu as subscribers “cut the cord”. The cable operator reported a drop in video subscribers for the tenth straight quarter in February.
