From what I've been able to gather, it seems that while TV's coveted demographic is 18-49, radio's is 25-54.
For example, ratings-oriented articles in TV trade publications seem to focus almost entirely on 18-49 numbers. And it seems that the most commonly accepted way of determining network rankings at various points of the TV season is to look at their 18-49 averages.
On the other hand, with radio, I've seen reports sent out by stations or station groups to their clients in a local market, and the only demo (besides 12+) mentioned is 25-54. Also, on these boards, the radio professionals who post constantly hammer home the importance of 25-54 numbers, with little or no mention of 18-49..
Given that the two mediums compete with one another (in addition to themselves) for ad dollars, is there any particular reason for this difference?
