>>word-of-mouth buzz but it seems the word-of-mouth only started when the format went off the air.
I don't know about word of mouth but when it came to publicity resulting from newspaper/TV pieces:
while it's true that there may not have been many billboards or any TV ads, there were more than a few
articles in both the Globe and Herald about Air America coming to town; Steph Miller's appearance (it was
on Ch 4 and was archived on their website--btw interesting trying to do a search for "CBS4" and "Stephanie Miller"--you turn up a lot of results, but only because their webmaster is named...Stephanie Miller), etc.
Apparently nobody saw this article in the Globe:
http://www.boston.com/ae/tv/articles/2004/10/01/air_america_finds_local_home/
Or, this one (a big article, front page of living section)
http://www.boston.com/news/globe/living/articles/2006/08/23/failure_is_an_option/
Or this Steph Miller interview from the Herald

>>Five minutes with ...Stephanie Miller By Dean Johnson
Syndicated talk show host Stephanie Miller will do tomorrow's and Friday's 9 a.m.-noon radio shows, heard locally on WXKS-AM (1430) and WKOX-AM (1200), from the WXKS-AM studios in Medford.
Or the many mentions in various papers, the Net, etc. Yeah, nobody knew about AAR Boston.
Actually the real problem may have been "nobody could hear it".
