DABetamax

Just read with some surprise an article over at the media Guardian – Report raises fears that DAB may be the next Betamax.

“The DAB platform of 2008, particularly in London, is already starting to resemble the AM platform of 1998, suggesting that DAB might have already been written off by the sector as a means to reach the ‘mass market’ audiences that national advertisers desire from the medium”

I have one question….  If DAB is Betamax, what is VHS?
