I would think as one gets down the list on rated markets, the opportunities for adopting a format like oldies increases. What we are seeing is fewer and fewer buys from advertising agencies the smaller the market size. With those dollars gone, the stations have to go after local business. Local business owners, likely on average, tend to be a bit older than the median age. The older adult, especially in the smaller markets, is seen as a quality consumer with the cash. It has never been about radio wanting to ignore the 55+ audience but it has always been about running a format that can pay the bills. In the big markets where the advertising agencies rule the dollars, if you're not a hobby, you find a way to get a share of those dollars if you don't want to go bankrupt or become one of the increasing number of 'leased' stations. The truth is, for radio, the 55+ audience has virtually zero interest for clients these advertising agencies represent.
