It's good to try Jazz on AM. It's a format that doesn't get much respect though it does have a loyal but small following.
Now that the sports format is landing on FM in most markets, it's time to rethink what format will thrive on AM.
My picks are:
1) CHEEZY FM
http://www.cheezyfm.com/ -- IN THIS CASE CHEEZY AM
2) Brokered radio - my friend makes a fortune brokering his stations to people that just want to be on radio-- he puts up lots of billboards with sayings like.. "Host Your Own Radio Program call..." , "Radio Personalities Wanted No Experienced Required" etc., I think half the population would like to have their own radio program... we all think we have something to say that people would like to hear...
3) Foreign language - another small but loyal following though Spanish radio has a large number of listeners- but you'll never get a true reasonable, Arbitron rating as many hispanics are illegally in this country.
4) Disney- kids are listening
5) Real community radio.. country store, a fishing program, polka, lots of remotes etc.. best example of that is WSNJ 1240 in Bridgeton, NJ

6) news
7) political talk - though I suspect owners will realize this format could thrive on Am as Sports has done.. I expect Rush, Hannity and the like will find a bigger audience on FM
8) I do like the idea of Jazz on AM-- run a satellite feed, bring in a couple of local guys/gals to augment & hire anyone that wants to sell radio (forget that last comment - every station owner is on the look out for anyone that has an interest in selling radio.)
