Radio is on the upswing, and in no arena more so than sports. Sports radio has always had a traditionally strong base of listeners, in large part because it's the most convenient way to know what's going on during a game at every moment, no matter where the listener is located – whether in the car, grocery store or even through headphones at an entirely different event. Accordingly, radio ads can have lucrative results on sports-oriented channels or during relevant shows, and the Radio Agency, specialists in radio advertising for over 20 years, has recently published a how-to guide regarding the best ways to approach this powerful advertising opportunity.
