It’s all very familiar at the top of the Media Monitors national chart for the leading advertisers on radio. The Home Depot ran another tidal wave of spots last week — 88,365 in all. GEICO put out a healthy 53,778. And there were no real shocks for the rest of the Top 5. Lowe’s was third (37,928), Progressive next (35,672), and the National Highway Traffic Safety Administration (32,572) all moved just one place either up or down.
