James L. Dolan, one of his sons, was the Cablevision CEO from 1995 until the 2016 sale to Altice. He now is the executive chairman and CEO of Madison Square Garden Sports Corp. The company owns the Knicks and Rangers franchises, among other properties, according to the MSG Sports website.

Newsday, which Cablevision purchased in 2008, also came under the control of Altice with the sale. Patrick Dolan, another son of Charles Dolan, led a group that repurchased 75% of Newsday Media Group in July 2016. Patrick Dolan then purchased the remaining 25% stake in 2018.

At the time of his death, Charles Dolan and his family had a net worth of $5.4 billion, Forbes reported.
