According to Phil Rosenthal, Tom Ehlmann, VP and GM of WGN- TV has been snagged by NBC. Also on the way out is Jill Manuel, news director of CLTV. Manuel and Ehlmann's loss is another sign of the bad times at the Tribune Co., which continues to hemorrhage talent. Saying he couldn't stomach more Chicago winters, Ehlmann is returning to Texas to manage some of NBC's operations there. Manuel has been hired as the news director of WEWS-TV in Cleveland.
