Charles Dolan, the billionaire creator of HBO, has passed away at the age of 98. He revolutionized television by introducing cable to New York in the 1960s and 1970s, initially selling specialized programming to hotels through his Teleguide service. In 1964, Dolan struck a deal with New York to install cable in select Manhattan buildings. To draw in viewers, he broadcast Knicks and Rangers playoffs, ultimately leading to the creation of Home Box Office. Later, Dolan sold HBO and his cable service to fund the development of Cablevision, which became a major provider of television and internet services in the northeastern United States. In 2015, Cablevision was sold to Altice for nearly $18 billion, with Dolan’s family at the helm of the business. At the time of his death, Dolan had a net worth of $5.4 billion, leaving behind a mixed legacy as both an innovator and a controversial figure among New Yorkers.
