What indeed is the future for AM? I don't know if the FCC would ever shut it down or if they'd
stop including AM on most radios (though some mp3 players have FM only; HD radios like my portable are FM only but have some AM signals like 1030 and 1200 on HD2, HD3, etc.)
Pluses include far ranging signals for some; minuses include static and electrical interference and some very weak signals...local "hometown" stations that might serve North Shore, South Shore,
Metro west--or are homes for ethnic or religious programming.
btw I was just in Baltimore and had my AM-FM walkman with me; listened to the O's game I
attended on AM 1090 WBAL. I think they're also on FM...on a sub-HD signal. The push is on to
put more sports incl. play by play on FM, but there's still quite a bit on AM. I was in Washington, PA
and the independent minor league Wild Things were on WJPA-FM 95.3...the AM side, WJPA 1450,
had the Pirates.
What will AM be good for...?
--Brokered, ethnic, religious
--Some sports especially networks (ESPN, Fox, Yahoo, NBC, some CBS...)
--Some political talk, news stations. (News on FM in some places...like "WNEW-FM 99.1" in DC
area)
--Children's (that means Radio Disney, like on AM 1250 in Pittsburgh. They used to be on
AM 540 around there but that's Fox Sports these days. I was in PA, WV, Maryland last week or so...)
--Some unique music formats with oldies or easy listening--like WJIB, WJTO, and an interesting station I found in the Hudson Valley. WHVW.

FM is still dominant but there's a place for AM
