“More saving, more doing… That’s the power of the Home Depot.” This mantra was heard 2,584,993 times over the airwaves last year, making the home center the No. 1 national radio advertiser for all of 2017. That is one step up from its No. 2 ranking in 2016, taking the place of insurance company GEICO, which retreats one slot to the runner-up position for the year. Its total: 2,208,419 spots. That’s marks a pretty substantial 376,574 spot count difference between the top two.
