BBC Radio 6 Music has hit record listener levels, and it has become the UK's first digital-only station to surpass 2 million listeners per week. Famously the station faced closure back in February 2010, ahead of a review by the BBC Trust – a campaign to save 6 Music, including a Facebook page with 180,000 fans and a general social-media-led public outcry, helped overturn the decision just 5 months later.

In May of 2010, perhaps due to the increased publicity from the campaign to save the radio station, it was revealed that in the first three months of that year there was an average of 1.02 million listeners – up from 695,000 for the same period the previous year.

Now it has been revealed that in the last three months of 2014 BBC 6 Music reached an average weekly listenership of 2.1 million. And with much of the UK not aware of 6 Music's existence, let alone listening to it, its controller (and controller of Radio 2), Bob Shennan, is optimistic about the figures rising still more:

"It is not going to be a mass mainstream station like Radio 1 or Radio 2 but the vast majority of the adult population still don't know about 6 Music," he said. "We will continue to look upwards to the next landmark, 2.5 million or something like that."

A quite rightly excited Lauren Laverne tweeted out the news:

Playing all sorts of music, from new finds by unknown producers to obscure slices of never-known sounds from anywhere and anytime, it's the kind of radio station that you can really get lost in. For instance, Lauren Laverne managed to secure an interview with the elusive William Onyeabor last year. It's a celebration of music in all its forms – you can check it out here:
