Share of ears

Another way of ranking radio stations is to look at their share of all the hours spent listening to radio in their target area.   In RAJAR terms, each station has a TSA (Total Survey Area), marked out to cover the agreed piece of the UK a station serves (not necessarily where it can be heard these days, with carriage on IP etc).  So, for example, Radio 4, serving the whole of the UK, has an 11.2 % share of weekly listening hours.  Radio 2 does even better, at 15.2% 

There is a BBC service that beats them both: Radio Ulster (including programming from Londonderry about to be severely reduced) at a remarkable 18.1%. No wonder they're on strike to try to turn round poor management decisions. 

While we're on, there are a number of BBC local radio stations with impressive scores against local, regional and national challengers. Radio Cornwall with 16.2% , Radio Guernsey with 13.1%, Radio Derby 10.2%, Radio Cumbria 9.9%, Hereford & Worcester 9.5% and Radio Jersey 9.2%.
