Marc Graboff is the latest NBCUniversal executive to leave the company since Comcast took it over in January.
The executive, president of West Coast business operations since August 2010, is exiting under "absolutely amicable" terms, according to an NBC spokesman, who said a mutually convenient timetable is being worked out for his departure. He had been at the company since 2000.
"He decided to pursue the next chapter of his career," the spokesman said.
Graboff worked under former NBCU CEO Jeff Zucker during his regime, negotiating talent deals. He now reports to NBC Entertainment chairman Robert Greenblatt.
In his current role, he oversees business and production-related operations for NBC and Universal Television. Prior to that, he served as chairman, NBC Entertainment and Universal Media Studios. He initially came to NBC in November 2000, as executive Vice President, NBC West Coast.
His tenure with NBC was preceded by a longtime stint as senior vice president of CBS Entertainment, a position he assumed in 1997.
Prior to his television career, Graboff was a partner at the law firm of Troop, Meisinger, Steuber and Pasich and a founding partner of the firm of Silverberg, Katz, Thompson and Braun.
