Yeah those 13p a minute calls really keep the money rolling in for talksport and the advertising revenue means fuck all to them.Not quite sure of the point you're making to be honest. All revenue is chased by them - you only have to listen for 5 minutes to ascertain that.
And it's not like it is one 13p call a minute. With 3 million plus listeners at certain times, it is not pie in the sky to think that there are many hundreds trying to get on air in that minute. Sitting in a queue, biding their time, as the money rolls in. Make the on-air subject contentious, and those numbers stay high.
