 Despite a loyal audience, the show's rather weak ratings, high production cost (the show cost $3.5 million to produce) and corresponding lack of ad revenue led to the show's demise after only a year and a half on the air.After news of this got out, some viewers sent in money help defray the costs of producing the program (all of which was returned).The 367th and final telecast of "NBC News Overnight" aired on December 3, 1983.
