The BBC has quietly dropped the award-winning BBC 1 science documentary brand QED.

QED, which aired as a science strand for 18 years, reappeared for its BBC 1 autumn run under the name Living Proof on Tuesday (21 September) with a story about a child with severe epilepsy.

QED/Living Proof series editor Michael Mosley said he had commissioned the current run under the old name before the decision was taken to rebrand the show.

Head of BBC Science Glenwyn Benson, whose department makes the strand, added that the QED brand was dropped because research showed the 'audience didn't have the faintest idea what it meant - which is not surprising because it's a Latin acronym'.

Benson dismissed any suggestion that Living Proof would focus more on human interest stories than QED. 'It's the same production team and the same content and stories,' she added.

But a BBC Science spokesperson said Living Proof would not have such a broad subject matter. 'It will take a specific hypothesis and try to prove it one way or another rather than talking round the subject like QED did,' she added.

Mosley also countered claims the strand was being marginalised because the first instalment of the new run went out at 22.20, as opposed to QED's previous 21.30 timeslot. He said this was just a scheduling issue and that next week's Living Proof will air at 22.00.

The rebranded strand has been extended from 30-minute to 40-minute episodes.

Five will air this autumn, with a further five commissioned for the BBC 1 winter schedule.
