Children's TV favourite In The Night Garden is facing the chop – because it is so expensive to make.
Warwickshire-based Ragdoll Productions said the 100 half-hour episodes had cost a staggering £14.5 million.
The programme has been a huge hit with children in 35 countries and earned its creators, whose headquarters are in Stratford-upon-Avon, a fortune through merchandising sales.
But the cash-strapped BBC was unlikely to invest in any more shows, according to Ragdoll boss Andrew Davenport.
Corporation bosses said the market was constantly being refreshed by children and it would continue to show episodes of the show.
There was good news for parents and toddlers in that Mr Davenport – who was also behind the Teletubbies – is developing a new show for TV and has not ruled out making a one-off episode if there is demand.
Richard Hollis, BBC Worldwide’s head of UK licensing, said the programme was the most expensive children’s programme commissioned and co-funded by them.
Describing In The Night Garden as “our biggest brand”, he said: “It was a huge commission for 100 episodes.
“But that quantity is probably enough as the market is continually being renewed by new children.”
Launched in 2007, the show became must-watch TV for pre-school children and made household names out of its characters including a blue teddy called Igglepiggle, Upsy Daisy, the Ninky Nonk train, Makka Pakka and the Tombliboos, whose trousers always fall down.
The show has attracted its fair share of controversy over the years.
Isaac Blake, a 28-year-old dancer who played one of the Tombliboos, claimed unfair dismissal at an employment tribunal and said he suffered discrimination because he was gay. And in January last year, parents complained that, while Upsy Daisy has dark skin on screen, an Upsy Daisy doll on sale in shops was whiter.
