Quoting a previous Hans . contribution:-

That is not BBC R1 and R2 then. They could easily be run commercially.

Here's an interesting one: The commercial sector always complain that were the BBC to run advertising on Radios 1 and 2, then the commercial sector's income would be drastically reduced. On various occasions they've put forward very convincing arguments as to why they don't want the BBC going commercial with their radio output.
