The duo's comedy follows the romance between an Essex boy and a Welsh girl
Gavin and Stacey writers James Corden and Ruth Jones have been named in the Guardian's list of the most powerful figures in the UK media.
The pair came 25th in the list, which was topped this year by Google creators Sergey Brin and Larry Page.
The X Factor's Simon Cowell was 14th, Doctor Who executive producer Russell T Davies was 31st and National Theatre director Nicholas Hytner was 34th.
The Guardian Media 100 was drawn up for the newspaper by 10 media experts.
The Guardian praised Corden and Jones as two of the UK's "brightest news comedy talents" describing their BBC Three sitcom - which follows the love story of an Essex boy and a girl from south Wales - as "one of the breakout hits of the year".
"Corden and Jones now have the sort of opportunities open to them that were enjoyed by Little Britain's creators Matt Lucas and David Walliams," the paper continued.
Cowell, who has enjoyed big success with his talent show formats in the US, rose six places from last year and was described by the panel as "hugely powerful".
"He could dictate anything he wants to the ITV network," they added.
National Theatre's Nicholas Hytner earned his 34th place for "combining cutting edge and populist productions, selling tickets for £10 and pioneering Sunday performances".
Writer and actor Stephen Fry was a new entry this year at 54 while Top Gear presenter Jeremy Clarkson rose 14 places to number 58 in recognition of his newspaper columns and best-selling books and DVDs.
Katie Price was praised for her ability to "shift product"
Radiohead singer Thom Yorke was also a new entry, at 63.
The Guardian said Yorke's band were responsible for the "marketing gimmick of the year" in October when fans were invited to put their own price on the 10 MP3 files that made up new album In Rainbows.
The paper said this had been "a watershed moment, an attempt to reinvent the economics of an industry struggling to cope with the impact of digital piracy".
Model Katie Price, also known as Jordan, was ranked 83rd and was praised by the panel for her ability to "shift product".
This included "reality TV shows, children's books, teenage novels, autobiographies, pop records or gossip magazines", the panel said.
Andrew Lloyd Webber was a new entry at 96 following his success as judge-in-chief for BBC One Saturday night musicals shows including I'd Do Anything and Any Dream Will Do.
ITV presenters Anthony McPartlin and Declan Donnelly, meanwhile, dropped 34 places to 99.
Piers Morgan is the author of two best-selling memoirs
The fall reflected a phone-in scandal surrounding ITV1's Ant and Dec's Saturday Night Takeaway, the Guardian said.
Former newspaper editor Piers Morgan - Cowell's fellow judge on Britain's Got Talent - scraped in at 100.
At the top of the list, Google creators Sergey Brin and Larry Page beat BSkyB chairman James Murdoch into second place.
BBC director general Mark Thompson was ranked third followed by Paul Dacre - editor-in-chief of Associated Newspapers - in fourth.
James Murdoch's father Rupert Murdoch, chairman and chief executive of News Corporation, was named in fifth place.
ITV executive chairman Michael Grade was ranked 11th while Channel 4 chief executive Andy Duncan was ranked 16th.
