Gavin & Stacey stars and creators Ruth Jones and James Corden collected the Judges' Award at the Royal Television Society (RTS) Programme Awards in London on Tuesday night.
Jones and Corden picked up the award after the final episode of Gavin & Stacey aired on Christmas Day after a gap of five years.
Presenting the award to Jones and Corden, writer and director Richard Curtis said: "In obsessing about viewing figures and competitive platforms and awards - although I love awards, obviously - we forget there are no real winners or losers - there's just creative people giving people things to laugh at, be moved by, be educated by, be comforted by - morning, afternoon, and night.
"So when the Gavin & Stacey finale went out - millions of us looked forward to it, and watched it - and by very simple maths - you and your team gave people in the UK 27 and three-quarter million happy hours. That's a huge thing - that's so much happiness - so many merry Christmas Days hyper-charged and so many ghastly Christmas Days fixed right at the end."
The Traitors and Strictly Come Dancing host Claudia Winkelman was honoured with the Outstanding Achievement Award.
RTS gave a Special Award for Television Journalism to journalists in Gaza for "their courage and commitment as they face extraordinary danger".
