"Pop-up" services
The BBC has experimented with short-term "Pop-up" digital radio stations, each broadcasting for approximately four days at a time, covering music festivals and other special events. The first to broadcast was BBC Radio 5 Live Olympics Extra in 2012, then BBC Radio 2 Eurovision launched for the first time in 2014, and was joined by BBC Radio 2 Country, BBC Music Jazz in 2015 and BBC Radio 2 50s in April 2016. When these temporary stations are on air, there is normally a reduction in bit rate of their parent station.
| Station Name | Description |
|---|---|
| BBC 5 Live Olympics Extra | Available during 2012 Summer Olympics with coverage consisting of sports commentaries. |
| BBC Radio 2 Eurovision | Launched in May 2014 to extend the BBC's coverage of the Eurovision Song Contest. Returned in 2015 to provide coverage of the 2015 contest. |
| BBC Radio 2 Country | Launched in March 2015 to provide coverage of London's C2C: Country to Country Country music festival. Returned in 2016 to cover the 2016 festival and again in 2017. |

Threat of station closures
In 2010, the BBC published plans to close BBC Radio 6 Music and BBC Asian Network.[3] These plans were later rejected, saving both stations from closure. Radio 6 Music was retained after listening figures increased and a campaign was set up on Facebook, which gained 180,000 supporters.[4]
Future services
In February 2024, the BBC proposed launching four services on DAB+ and BBC Sounds. The services will be sister stations to BBC Radio 1, BBC Radio 2 and BBC Radio 3, plus BBC Radio 1 Dance. The plans are subject to the relevant regulatory approvals, including a Public Interest Test for the proposal to launch the stations via DAB+, a process which the BBC will start in the coming weeks and is expected to run until the end of 2024.[5]
