The BBC could be set to axe its Saturday night show So You Think You Can Dance unless the series pulls in more viewers, it has emerged.
The BBC One show, which is hosted by Cat Deeley, was seen by just 3.63 million viewers in its first live final on Saturday.
Britain's Got Talent, which featured a new judging line-up without Simon Cowell, attracted 10.4 million viewers on ITV1.
BBC bosses are hoping that So You Think You Can Dance, which features Louise Redknapp, Arlene Phillips and Nigel Lythgoe on the judging panel, does better this weekend when it is aired immediately after the new series of Doctor Who.
So You Think You Can Dance has been a success in the US, where it is also hosted by Deeley.
It launched in Britain with 6.4 million viewers and the second series, which still has several weeks to go, kicked off with 4.8 million.
A source told the Daily Mirror: "It looks as though viewers have got bored of So You Think You Can Dance, which has gone into freefall in terms of viewing figures.
"Producers are struggling to halt the decline, and senior bosses have lost patience with the format. It's unlikely there'll be another series."
A BBC spokesman said: "So You Think You Can Dance is only four shows into its 12-week run. No decision has yet been made on the next series."
