GEICO broke The Home Depot’s long run atop the Media Monitors list of the top 100 radio advertisers last week. But it was just a blip on the radar, apparently, as the home improvement giant is back at number one, running a massive 90,800 spots in the past week. GEICO was second but ran only half that number of ads — 45,971. Familiar faces rounded out the top five. Third was Lowe’s (34,147), followed by Progressive (31,606), and McDonald’s (27,765). Macy’s and Indeed were knocking on the door.
