The BBC is hoping to bring back BBC Three as a regular TV channel, four years after it was taken off air and moved online.
The youth channel, which commissioned hits like Normal People and Fleabag, will also have its budget doubled.
It left linear TV in 2016 to save £30m, and because the corporation said young people were watching more shows online.
The BBC now says it is “considering the case” for returning the channel to “linear television”.
A BBC spokesman said “we’d be wrong not to back a service that is doing better than anyone could have ever conceived”.
The turnaround will be formally announced as part of the BBC’s annual plan on Wednesday, but there was no news about the fate of BBC Four, which has been rumoured for the axe.
The corporation warned that putting BBC Three back on TV will mean reductions in other areas, especially as the BBC’s income has been reduced by £125 million during the coronavirus outbreak.
But it says those decisions won’t be made until the autumn when there is a clearer picture of the BBC’s finances.
However, the BBC did say it had no plans to close BBC Four at the moment.
BBC Three launched in 2003 and made its name with hits like Little Britain and Gavin & Stacey.
In recent years, it has also been behind comedy and drama successes like This Country, People Just Do Nothing, My Left Nut and the Bafta-winning Killed By My Debt.
It has also made the reality shows RuPaul’s Drag Race UK and Glow Up; as well as hard-hitting documentaries like Stacey Dooley’s investigations and Jesy Nelson’s Odd One Out.
Normal People, an adaptation of the Sally Rooney novel, recently propelled BBC Three to its biggest ever week on iPlayer, with 21.8 million requests for the channel’s programmes.
Its shows have been aired on regular TV as well as online, including in a dedicated zone on BBC One after the News At Ten since last spring.
When it moved online in February 2016, the BBC Trust said “independent evidence shows younger audiences are watching more online and watching less linear TV”.
But BBC Three reached 8% of British 16-34-year-olds per week in 2018/19, down from 22% in 2015/16.
The BBC now says its research shows there is a potential large linear audience for the channel’s programmes, which it says are reaching both young people and the wider audience in “big numbers”.
The news comes two months after director general Tony Hall told MPs the board was looking to “divert more resources into BBC Three to build the kind of creative content they’re delivering”.
But with the corporation needing to make savings, there has been speculation that BBC Four may be among the casualties.
A petition calling for the channel to be saved has attracted more than 58,000 signatures.
