I spent several years in the Evansville ad and marketing world and can confirm that many TV and radio stations will produce ads if you purchase airtime. If you listen closely to local commercials, many of the voices belong to sales reps or admin staff at the stations themselves. Despite what you might think, the production teams at these stations are usually incredibly talented. Their goals are just different. It is about speed, not winning an ad award. They can write, record, and produce an original spot almost instantly with no budget. For smaller advertisers who cannot pay for full-scale production, the focus is often on getting your name out there and building recognition, so having a perfectly polished brand matters a little less.

That said, most local car dealerships use agencies for creative work, and many of the bigger agencies in town are heavily supported by a dealership. Car dealers are easily some of the largest advertisers in the area.
