Doh! 'The Simpsons' back for 2 more seasons

Doh! Big-screen success hasn’t jaded Homer, Bart, Marge, Maggie and Lisa. They’re going to stay on TV for a long time, Fox announced today.

The network renewed “The Simpsons” for two more seasons. That means 44 additional episodes after this season, bringing the show through its 22nd season and 493rd episode. "The Simpsons," created by cartoonist Matt Groening, debuted as a regular series on Jan. 14, 1990 after a Christmas special on Dec. 17, 1989. It first appeared in 1987 as a series of 30-second shorts for “The Tracey Ullman Show.”

Fox currently is showing its 20th season at 7 p.m. Sundays. In Sunday's episode, “How the Test Was Won,” Bart and other “underperformers” at his school are sent to Capital City by officials to avoid them bringing down standardized test scores. Meanwhile, Homer has to avoid getting injured when his insurance lapses.
