Cablevision Systems said video subscriber losses in the first quarter doubled from a year ago, as the cable TV company's customers continued to shift to lower-priced bundled services from telecom carriers.
The company, which operates primarily in the Greater New York area, also reported a smaller-than-expected quarterly profit as technical and operating costs increased.
Cablevision lost about 28,000 video subscribers in the first quarter ended March 31, up from the 14,000 it lost a year earlier.
The company has lost video subscribers for 11 consecutive quarters now, as it struggles to fend off competition from telecom companies such as Verizon Communications and AT&T, which lure away subscribers with bundled telecom and satellite TV services at competitive prices.

Cablevision, under pressure to stop consumers from "cutting the cord" and shifting to internet video services such as Netflix and Hulu, has said it would offer HBO's standalone streaming service, HBO Now, and Hulu's video streaming service to its broadband customers.
