hmmmm, difficult one.
i have, i shall confess, some difficulty with the way the BBC - as the public service broadcaster - mirrors the output of the commercial broadcasters but with the public service broadcasters coin.
in effect, i believe that the BBC should do the things that the commercial broadcasters can't, or won't, that are in the 'public interest' - so kids tv without adverts or product placements, the news and investigative journalism/current affairs stuff that just cost too much for commercial organisations to produce, the challenging/interesting documentaries, drama, film and comedy that the advertisers won't be interested in sponsoring etc..
i don't see why the BBC needs its own version - exactly the same in content, but with a BBC label - of i'm a strictly celebrity dancing on ice, or the voice factor, or soaps, or whatever D-lister wants to plug their book/film. all that stuff is on free-to-air commercial tv, its already being done, there's no hole to fill.
does Radio 2 fill a hole that no free-to-air commercial broadcaster will fill? to me it seems completely mainstream with nothing differentiating its product from any other radio station i get while going (or sitting still..) on the M6. Radio 4 is the complete opposite, with Radio 1 perhaps somewhere inbetween with its not-available-on-commercial, public service stuff in the evenings, but during the day its no different to Heart or Capital.
it would be interesting to see how much cash and airtime would be available if the BBC ditched its ITV/freeview clones and waste -of-electricity-dross (cash in the attic anyone?) and reformed its Byzantine management structure - what impact would that have on comedy, drama, natural history etc...?
