Channel 4 reported a £26m surplus for 2016, with £20m of this allocated to the content reserve.
Meanwhile £629m was spent by Channel 4 on content, of which £455m was spent on originally commissioned TV, film and digital content – both record amounts.
David Abraham, the chief executive of Channel 4, said: "Channel 4 had a record impact on audiences and the UK’s creative sector in 2015 with our investment in original content, our commercial revenues and, critically, the delivery of our public service remit, all at their highest ever levels.
"We expect this impact and growth to continue in 2016 and, as a wide range of independent experts have concluded, our focus on both creative and commercial innovation has positioned us very strongly for the future."
