This is from  "Advanced Television".

The BBC will return nearly half the £600 million (€734m) fund it was given to help the elderly and disabled convert from analogue to digital TV after the switch proved more straightforward than many people had feared.

A total of £603 million was allocated out of licence fee revenues to help the over-75s, the blind and partially sighted and with other serious disabilities get digital TV.

Eligible households were given free help to convert one set, but the total cost has been much cheaper than the original projection which was at the top end of expectations and at a time when digital take-up was much slower.

The BBC, which has helped nearly 1.2 million people to date, expects to return almost £300 million of the £603 million fund to the government, substantially higher than previous estimates of a £250 million underspend.

The money will be spent on broadband rollout and culture secretary Jeremy Hunt’s plan to develop new local TV services across the country.

... and it's perhaps the last thing we need! DAB is so poor aurally - aptly because of the low bit-rates which DAB can allocate to the various services. FM blows its socks off!
The UK will probably be one of the last to change to DAB+ (having gone down the blind alley of DAB first - with its MPEG-L2 coding - of course). At least the TV people realised that DVB-T was unable to deliver HD services and were able to get T2 implemented before everyone had bought their Freeview STBs! Radio Management, which has known since the mid-90s that DAB was going to be very limiting, has failed to get anyone to agree to switch to DAB+ (with its much more efficient coding) hoping instead that having more multiplexes would allow them to allocate more CUs to the services so as to improve the quality. Now they've scared many old folks into buying digital radios with the rumour of turning off analogue radio 'soon' just to get the number of digital radios sold to show a significant increase.
Foxy's right, that improving DAB reception will indeed cost a fortune. They have to add many more transmitters, and up the power of those they already have!!
DRM - another (better?) alternative to DAB - was never given a 'proper test' in the UK.
However, one person who's worthy of praise in this mire is Rupert Brun, who arranged for the Electric Prom concerts last year to be broadcast over the net using very much higher bit-rates (and consequent improved quality!). Let's hope he's allowed to repeat again this year.
