A veteran TV Exec has decided it's time to take a bow.

After 40 years, CBS exec Bruno Cohen says he's retiring. Cohen has led KPIX-TV in San Fran, KOVR/KMAX in Sacramento and WBBM in Chicago.

Cohen actually worked at KPIX from 1979-1986 as EP and then news director.

Before joining CBS, Cohen was Senior VP at CNBC.

According to CBS Television Stations president Peter Dunn, Cohen will continue at KPIX until CBS finds his replacement.
