Cablevision

Cablevision Systems Corporation was an American cable television company with systems serving areas surrounding New York City. It was the fifth-largest cable provider and ninth-largest television provider in the United States. Throughout its existence and in its final years, Cablevision exclusively served customers residing in New York, New Jersey, Connecticut, and a small part of Pennsylvania. However, at one time it provided service in as many as 19 states. Cablevision also offered high-speed Internet connections (Optimum Online), digital cable (Optimum TV/IO Digital Cable), and VoIP (Optimum Voice) phone service (the eighth-largest telephone provider in the U.S.) through its Optimum brand name. Cablevision also offered a WiFi-only mobile phone service dubbed Freewheel. On June 21, 2016, Cablevision was acquired by European telecom conglomerate Altice. The former Cablevision services operate under Altice USA which continues to operate brands Optimum Online, Optimum Voice, and Optimum TV. In the mid-1960s, Charles Dolan built a cable system called Sterling Manhattan Cable in the borough of Manhattan and launched Home Box Office (HBO). He ended up selling both the cable system and HBO to Time Life Inc. He used the money to start a new cable system in suburban Long Island called CableVision. Cablevision, having changed its name from CableVision, quickly expanded by building on Long Island and acquiring smaller cable systems from other providers. Cablevision also built systems throughout the New York metro area: some of the other boroughs of New York City, New Jersey, Westchester County, and Connecticut. In the 1980s, Cablevision also expanded into the Chicago, Boston, and Cleveland areas. By the mid-1990s Cablevision would offer service to 2.9 million subscribers in 19 states. Through a series of transactions in the late 1990s, Cablevision decided to consolidate their cable systems into three core areas: New York, Cleveland, and Boston. Despite reducing the number of areas served they were able to bring the number of subscribers to 3.
