Fox Television has confirmed that they have a deal to keep the show going until at least 2005.
This will take it to the end of Season 16, meaning around 50 new episodes.
The news will please CBBC Newsround users: you voted the show your favourite TV programme every week last year in Your Charts.
And we've also launched a new Simpsons message board so you can chat about The Simpsons and meet e-buds as much as you want.
More episodes on Channel 4
The Simpsons was first shown as a half-hour show in 1989, although it started life two years earlier as a short cartoon in The Tracey Ullman Show.
But it's hardly ever off our TV screens, with BBC2 showing older Simpsons episodes at 6pm every weekday.
And next year, Channel 4 will start showing new episodes from Season 12 onwards.
But it's paid a tough price for the privilege - more than £500,000 per episode.
