Dolan’s early ventures included wiring Manhattan buildings with cable in 1964, and subsequently, securing broadcast rights for New York Knicks and Rangers playoff games to draw in viewers. His work culminated in the creation of HBO, which became synonymous with premium content, attracting a vast audience across the nation. The Dolan family eventually sold Cablevision to Altice for approximately $18 billion in 2015, with James Dolan at the helm, continuing the family's prominence in the industry. Despite having a net worth of $5.4 billion at the time of his passing, the Dolans have often been at the center of criticism from fans, particularly relating to the performance of the Knicks and contentious programming decisions that occasionally alienated customers.
Television's evolution owes a considerable debt to Dolan's pioneering efforts, and his influence will be remembered as a cornerstone in the history of media enterprise.
