AOL Huffington Post Media Group has won the prestigious Association of Online Publishers (AOP) award for Pureplay Digital Publisher 2012.
The prize, which recognises innovation and creativity online, comes just one day after HuffPost UK celebrated its first birthday.
Held at Camden's Roundhouse, London, on Thursday night, the event was hosted by comedian Chris Ramsey.
The AOP judges commended AOL/HuffPost on its "very strong product portfolio" saying: "They are market leaders that have shown strong growth over the past year.
"On a number of initiatives they are leading the market. Strong strategic vision and measurable execution."
The awards ceremony, now in its 11th year, celebrates "innovation, entrepreneurial success and digital dexterity".
John Barnes, AOP chairman, said the awards marked a "new era in digital publishing".
“I didn’t think we could surpass last year’s amazing event, but we did, thanks to the superb efforts of our incredibly talented and resourceful industry," he continued.
"The sector continues to go from strength to strength.
"This year’s awards mark a new era in digital publishing, where media owners are building better digital businesses and where innovation and entrepreneurial excellence are developing new revenue streams and creating wealth across the sector and beyond.”
Noel Penzer, Managing Director UK, AOL Huffington Post Media Group, said: "As we continue to turn AOL around as a business, the strategy and focus we have across our consumer media properties is paying off.
"We are seeing good growth in the UK across the key areas of our consumer media business - both in terms of key sites and also with advertising. This award is great recognition to the business and all the teams involved."
Carla Buzasi, Editor-in-Chief of AOL & The Huffington Post UK, said: "A lot of hard work has gone into all our sites in the past 12 months, so it's great to be recognised by the AOP.
"That the award comes in the same week that we celebrated HuffPostUK's first birthday, makes it extra special."
Other winners on the night included NME.com, Guardian Music, and Sky.
