Who saw this coming? In a quieter week in national radio advertising, Media Monitors has listed job search site Indeed, which aired 35,815 ads last week, as the leading advertiser in the country. Home Depot has slipped down the chart from top spot, while GEICO returned to the “leader board” but could only get to second place with 34,941 spots aired. Sprint was third (33,728), followed by another surprise: The Ron Burgundy Podcast (30,715). Progressive rounds out the top five with 30,246 ads on the country’s airwaves last week.
