Groening to end The Simpsons

The Simpsons creator Matt Groening is desperate to end the hit TV show because he's running out of new ideas for the animated family.

The cartoon is about to start its 16th series in the US but Groening insists he will only do three more series after that, and will officially finish in 2008 with 365 episodes, to beat America's longest-running programme Gunsmoke, which ran for 20 series.
