TELEVISION

Series Premiering Poorly: Premieres of the NBC sitcoms “Men Behaving Badly� and “Jenny� settled for fourth place in their time periods Sunday, according to preliminary results from Nielsen Media Research. ABC’s revival of “The Wonderful World of Disney�--launched with the hit movie “Toy Story�--also got off to a so-so start, attracting roughly 9.4 million homes. While that’s an increase compared to what “America’s Funniest Home Videos� and “Lois & Clark� averaged last year, it’s also a significantly lower rating than the network scored with “The Lion King� last November. CBS’ “Touched by an Angel� remained the night’s top-rated program, reaching nearly 15 million homes.
