Other channels were trying to buy the show too so the price went up and up and just got too "ludicrous", says the BBC.
Too much d'oh!
The BBC buys programmes with cash they get from licence fees. The public pay for a licence so they can watch TV.
But they felt they just couldn't spend so much of that money on the cartoon.
Episodes of the unconventional Springfield family were costing around £100,000 each until now.
As different channels tried to bid for the new episodes, the cost went up to more than £700,000.
Channel 5 and Channel 4 are still in line to buy the shows though.
But don't eat your shorts just yet. Your favourite TV programme will still be on BBC2 until the end of 2006, with three new series and repeats.
