Scarborough, the longest serving anchor in New York's history, called his time at the network "historic," a source with knowledge told The Post.

Chuck Scarborough, an institution in New York broadcasting, has been reporting the news for half a century. On Dec. 12, he’ll say goodnight to viewers for the last time as anchor on WNBC. Scarborough, 81, is retiring after more than 50 years at NBC.

There are believed to be only two anchors in the United States who have done this job longer — Dave Ward, of Houston's KTRK/13 (who retired in 2017 after 51 years) and Don Alhart, of Rochester's WHAM/13, who hit the 50-year mark in 2016 and retired this past June.
