dying

I think it's a tell of a struggling medium when it advertises the fact you can advertise with them. I imagine their advertising revenue can't be too successful if they have no ads to place in that media space. You see it all the time on websites with banner ads suggesting one could "advertise here". It's also pretty popular on the inside of trains. And I realised today, that radio has been doing it for a while with a pretty heavy push lately. Is this the sign of a dying medium, or at least a profitable one? And how long until we see a major television networks running similar ads?...
