Tom Capra abruptly resigned Friday as general manager at KTTV, the Fox-owned station in Los Angeles, after a little over a year in that position.Capra, the former exec producer of NBC’s “Today” show and news director at local O&O KNBC-TV, cited a desire to go back into production. The exec spent a year under a development deal at NBC Prods. between leaving “Today” in November 1991 and beginning his tenure at KTTV. “I want to see my product on the air,” he said. “I didn’t realize how much I missed it.” Capra notified staffers of his decision Friday. Mitchell Stern, president/chief operating officer of the Fox station group, will oversee KTTV in the interim. A likely candidate to replace him may be Terry Crofoot, who spent five years as general manager at KABC-TV, and joined the Fox TV Stations as VP of news in November. Crofoot was hired under a mandate to work with Fox’s general managers on strengthening their news programming. During his tenure, Capra brought aboard several former KNBC news colleagues in key positions at KTTV, among them anchor John Beard, reporter David Garcia, “Fox News at 10″ exec producer Nancy Valenta and “Good Day L.A.” exec producer Kim Friedman.
