POTUS, Fox new 15 minute news channel, the liberal Indiana Talks now only on the Internet, the WINS or KYW format, "Give Us 15 Minutes, We'll Give You the World", the CBS long form news format on WBBM or WCBS, Bloomberg Business Radio, Inspire Radio on Sirius/XM, Business Radio Network or anything your creative minds can come up with. How about an all talk show, like WGN with different creative hosts? The big picture is lowering interference and the noise level on AM which may mean additional rules on power companies and electronic manufacturers that only government can do. I will leave the subject of digital broadcasting to broadcasters.
I worked for Emmis when they owned television stations and called on local advertisers. The age question was never a problem with local advertisers but yes it was on regional and national. In radio, demographics seems to be more of a factor for placing a buy. In a recent article in the AARP magazine, a critique was leveled on the whole premise of concentrating on young demographics and the fallacy of young people developing buying habits in today's world.
I am not criticizing Emmis, I am commenting on the general state of the AM radio situation.
