How much original programming does BBC 4 actually produce anyway? Last thing I recall watching that was original was Brain Pern and before that it was Screenwipe. The vast majority of the channel's content is Scandi crime imports, Bob Ross and repeats of old music programs, history documentaries and Attenborough.
Wouldn't mind if it intends on just showing repeats from the BBC archives, there's plenty the BBC have to show. Have it go 24 hours too.
