118. Charles Dolan & family
Dolan, a cable pioneer, owns controlling stakes in AMC Networks and Madison Square Garden, plus NBA’S New York Knicks and NHL’S New York Rangers. He left John Carroll University and went into media, first creating sports newsreels for TV stations from his Cleveland home. After moving to New York in 1952, Dolan made industrial films, then, in 1965, wired Lower Manhattan with cable and founded the predecessor to HBO. Eight years later he sold HBO to Time Inc. and launched a Long Island cable company with 1,500 customers. He grew it into Cablevision, which French billionaire Patrick Drahi’s Altice acquired for $17.7 billion in 2016.
