Input: Question: What is the current age of the chairman of the MSG Network who fired Marv Albert? Passage:Marv did his first Knicks game on January 27, 1963 on WCBS Radio. He filled in for his mentor, Marty Glickman, who was away in Europe. The game was against the Celtics at the Boston Garden. For 37 years beginning in 1967, Albert was the voice of the New York Knicks on radio and television (getting his start by being a ball boy for the Knicks before getting his first break on New York radio by sportscaster Marty Glickman) before being let go by James L. Dolan, the chairman of the MSG Network and Cablevision, after Albert criticized the Knicks' poor play on-air in 2004. It was said that Marv's high salary was also a factor. His son Kenny Albert has been a part-time play-by-play announcer for the Knicks since 2009, whenever the older Albert's successor Mike Breen (whom he later followed on the NBA on NBC broadcasts and now works on ESPN and ABC aside from his role at MSG) is unavailable.
