Jennifer Dorian, general manager of TCM, announced Osborne's death Monday. A publicist for the network said he passed away Monday in New York.
Osborne, who began his career as an actor, was a columnist for The Hollywood Reporter. He was the on-air host of Ted Turner's fledgling classic movie network from its inception in 1994. He was there from the start, to introduce "Gone With the Wind," and remained Turner Classic's primary - and often sole - host since.
