Part of this has to be that some companies have found out that a lot of mass media advertising just does not work: for some businesses it does, if they can afford a LOT of ads, but I sometimes hear or see ads for little mom and pop businesses that draw from a small corner of the county yet they are paying for reach a whole bunch of folks who would never ever patronize them. When I was in radio I used to have business owner friends ask me about radio advertising and I'd tell them, "Don't quote me on this, but why waste your money?"
