Why do we need BBC3 and 4.......
...plus two other part time channels devoted to kids TV?
Why not pull the content used for all 4 channels into one 24 hour channel?
Most of the content for 3 and 4 is repeats so merge the channels into one and use the spare bandwidth to boost the bit rates on whats left (BBC1/2/3)
Then there are the Red button channels that appear to have very little going on......get rid of some of them.
BBC Parliament? Does that have to be a visual channel? Switch it to a DVB radio channel instead.
It all costs money but the BBC seems to have an attitude of "use it or lose it!"
Less is more chaps, remember that. Talent and quality will out!
