Bob Morse resigned as vice president and general manager of KTTV Channel 11 Monday to take the top position at WMAQ-TV, the NBC-owned station in Chicago.
Robert Kreek, president of Fox Television Stations, will serve as acting general manager of KTTV until a replacement for Morse is hired, a Fox spokesman said.
Morse, who took over the reins at KTTV in late June, 1987, said he was leaving because the opportunity to work at a network-owned station in one of the nation's three largest TV markets "doesn't come along very often."
A former TV news director, he said he was also lured by the fact that "Chicago is a great news town." Twice as many viewers watch TV news there as in Los Angeles, he said.
Morse's biggest goal at KTTV had been to make Channel 11's 10 p.m. newscast more competitive, and he said his proudest accomplishment during his year at the station was the Emmy Award it won last May for the best regularly scheduled daily news program in the Los Angeles market.
Before joining the Fox-owned station here, Morse was president of WHAS-TV in Louisville, Ky.
