As long as I can remember, the two overall sales demos were 18-49 and 26-54. That does not mean all campaigns were against these demos, though. That means nearly all campiagns are either the entire demo or portions totally contained within them, such as men 25-44 or women 18-34 or persons 25-34.
Change comes as marketers redefine the demos that thier products appeal to, not as a decision of an industry association or group of expers. So, what one sees is that, over perhaps a decade, there might be less 18-34 and more 25-44 buys coming out... and the changes are indeed that gradual.
There used to be more 12-24 and 18-24 buys than there are now, but in all cases, that was never a big demo... thus the tendency of CHRs in the last 20 years to use teens only as a building block to get young adult women. Similarly, there are seldom any buys for 55+ or even 45-64 or ranges that include over 55. This is why stations try not to appeal too much to over-55.
Interestingly, 12-17 and 55+ are the two demos where radio is losing some ground, gradually. This is not surprising as the industry does not pay any attention to these demos as they are economically non-productive.
