Thank you for the warm welcome CHRles! I'm new & loving the debate here!
I like you, do appreciate the "thinking out of the box", something we often times lack here in Little Rock, but I will say for advertisers to support a local radio station they want to see traffic through their doors as a result of their radio advertising investments. There's no greater format to bring in live-remote traffic than CHR, Hot-Chr, or Urban formats. The demographics that listen to those stations will follow the DJ's & radio stations without necessarily having a "star or celebrity" show up at the live-remotes. Now... will this demographic by a new "Sub-Zero" refrigerator/freezer? Highly unlikely, but they do purchase food, cars, jewelry, clothes, CD's, electronics, video-games, beauty products, fitness equipment, athletic apparel/accessories, and etc...
What I'm saying is... I would think that whoever is deciding the formats should keep in mind which formats drive customers to the point-of-purchase. Small business is what keeps this country's economy in check.... The more satisfied advertisers, the more revenue generated for the station.
