Marc Graboff Leaving NBC

Marc Graboff, president of West Coast business operations for NBC Entertainment, is exiting the company, a network spokesperson confirmed late Friday.

NBC and Graboff are working on a "mutually exclusive" departure date and entertainment chief Bob Greenblatt will decide whether or not to replace him, the spokesperson said.

Graboff, a longtime NBC executive, had taken on his current role in August 2010, prior to Comcast's acquisition of NBC Universal last January, which saw many executives depart once Greenblatt took control of the entertainment division.

He previously served as co-chairman of NBC Entertainment with Ben Silverman from 2007-09. He first joined the network in 2000 from CBS.

The news was first reported in the Los Angeles Times.
