Table - Radio Revenues

Radio ad revenues grew marginally in Q3, up 1% year-over-year to reach $4.6 billion, according to the latest quarterly revenue report [PDF] from the Radio Advertising Bureau. That still managed to be the best result so far this year, following flat revenues in both Q1 and Q2. Digital continued to be the fastest-gaining radio sector, up by 19% year-over-year, but remains the smallest revenue-driver. Spot, the largest, saw a 1% increase in revenues year-over-year, but is flat for the year-to-date. The study finds wireless carriers continuing to invest more heavily in the medium.

In Q3, the communications/cellular category increased its spending by 24% year-over-year, led by AT&T and T-Mobile, which hiked their expenditures by 56% and 62%, respectively.

Edging that category as the biggest spender in Q3 (by a small margin) was automotive, which was led by Ford Dealer Association (+14%) and Toyota Dealer Association (-11%). The most rapid spending increases within the category came courtesy of Honda Dealer Association (+65%), Ford Motor Corp. (+54%) and Nissan Motor Corp. (+45%). Read the rest at MarketingCharts.
