Does anyone see a future with AM radio? We're already down to basically 3 relevent AM stations in Boston now. WEEI, WBZ, and just hanging on is WRKO.
Fascinating question. My short answer is "yes - for certain signals, for a while." Extrapolate out 25 years and, yes, things look a lot more dire.
Basically, the smaller AMs around the market are in pretty bad shape long term. There's plenty of blame to go around for that too. The FCC for overcrowding the band, the emergence of new technologies that render AM obsolete, our good friends at Ibiquity for jamming what's left of the band with hash, too many AM owners chasing a fast buck with poor programming choices that no one listens to (infomercials, dollar a holler, etc.).
Thanks to all of this, the smaller signals are doomed.
However, the more powerful 50 kw signals are not. A signal like WBZ still has great value and still brings in solid revenue. If you look at top billing stations in the US, there are still plenty of AMs on that list of top 100 stations. But pretty much all are 50 kw signals with solid market coverage day and night.
Bringing this back to Boston, WBZ is in good shape for a long time to come thanks to programming. WEEI has been strong thanks to programming. And, WRKO is waning thanks to programming and piss poor programming/staffing decisions by Entercom. It's not waning because it's an AM signal and it's not waning for carrying Rush Limbaugh and Howie Carr. Those are the station's strong points. The rest of the schedule is a mess and the imaging has gone in the crapper over the past 5 years. It's nothing that a good ol' house cleaning of management couldn't fix - and the station, if on FM, would still be in the crapper.
But you're right in that there are very few viable AM signals in the market: WBZ, WRKO and (marginally) WEEI are about it. However, things need not be that dire for the entire AM band....not yet. If the FCC would get a clue and stop ignoring the physical principle of skywave (and license stations as such), and if they would start cutting down on the number of AM signals in each market; well, that would help. The cessation of IBOC on AM would help too. Perhaps opening up the band between TV channels 5 and 6 to relocate local AM signals would help by clearing up the band. Dump the graveyarders and hangers-on to formerly clear frequencies onto low FM. Simple 100 watt signals that serve their areas.
If the AM band had a lot fewer signals, favoring the strong former clears, that would extend the life of the band significantly.
