The BBC's Ruth Caleb received an award for her outstanding contribution to British TV.
The channel walked off with 11 awards on Sunday, including Best Comedy Programme, Best Situation Comedy, Best Documentary, Best News and Current Affairs Journalism and Best Drama Serial.
ITV's Emmerdale won the award for Best Soap, while the channel also won the Best Factual Series award for Britain At War In Colour.
Graham Norton's double win came after winning last year's Best Entertainment Performance award - and his Channel 4 counterpart Sacha Baron Cohen won the Best Comedy Performance and Comedy Programme awards for his creation Ali G.
Norton, 38, said: "I'm so pleased the show has won a prize. It's brilliant."
Baron Cohen adopted a mock Shakespearean style when he picked up his first award of the night.
"Playing the role of Ali G has been such a challenge. He's such an exuberant fella," he told the audience.
"If he was here he would no doubt say something along the lines of 'Boyakasha', or 'Respect' or something like that."
The channel's historical serial Longitude won Best Drama Serial and also provided Sir Michael Gambon with the Best Actor award.
The BBC One film Last of the Blonde Bombshells landed Dame Judi Dench the title of Best Actress, while Louis Theroux picked up the Richard Dimbleby Award for Best Presenter for his BBC Two series Weird Weekends.

Director of drama and entertainment at the BBC Alan Yentob said he was delighted with the BBC's awards.
"The resounding success of Clocking Off, the remarkable Care and the accolade for Ruth Caleb and Dame Judi Dench proved that the BBC is still paramount in this genre."
There were a number of special awards, one of which went to the ITV soap series Coronation Street for its 40th year on air.
