Analogue went off a while back in the UK, for years the manufacturers were coining in on this selling "Digital Ready" Aerials and what not, fooling people in to thinking their aerial needed to be replaced, their TV needed to be replaced etc.
Just like "CD Ready" on headphones in the 80's haha!
Digital TV is all about more revenue here, let's see how many channels we can fit on the multiplex with as little bit rate as possible, even the HD channels have taken a bitrate hit over the past few years.
Now there is a new money spinner, 4G mobile networks interfere with DVB-T/DVB-T2, so more aerials are sold and passive filters.
DAB is a waste of time, lesser audio quality than FM due to bit-rate on the majority of channels, everyone uses FM especially in vehicles.
Plus DAB is based on a well out of date codec.
