Chevrolet garnered ad impressions from March Madness, PGA Tour golf and World Baseball Classic.

Chevrolet continues to up its investment in its “Best-Selling” spot highlighting various Silverado models: According to, the automaker increased its estimated TV ad spend for the spot 37.7% week-over-week, which resulted in a 9.7% increase in TV ad impressions. Sports were a key focus, with men’s March Madness games, PGA Tour golf and the 2023 World Baseball Classic as the top impressions-driving programs.

With 183.7 million impressions, Hyundai’s “Getaway Sales Event” spot takes second place, down from first the previous week. The Big Bang Theory was the top impressions-driving program (8.6 million impressions), followed by SportsCenter (6.9 million), PGA Tour golf (6.3 million) and the 2023 World Baseball Classic (5.4 million). According to iSpot’s Creative Assessment, this ad scored above the auto industry norms for likability, information, desire and relevance. 

In the fast-paced No.3 ad, Dodge declares it’s “taking the nation by swarm” with the new Hornet. This spot generated 157.6 million TV ad impressions during the week, with 15% coming from men’s March Madness games. Per iSpot’s Creative Assessment, 29% of surveyed viewers said the product itself was the single best thing about the ad. 

“Make Your Dream Car a Reality” from Mercedes-Benz takes fourth place with 135.5 million TV ad impressions. The sleek cinematics resonated with viewers: 33% of iSpot Creative Assessment survey respondents cited the visual scenes as the single best thing about the ad. This commercial had the lowest TV ad spend (est. $868K) of the top five and, unlike the other brands in our ranking, Mercedes eschewed a sports-heavy approach in favor of news programming: The Five, America Reports and Anderson Cooper 360 were the top shows by impressions, while Fox News and CNN led for impressions-generating networks. 

Buick’s fifth-place spot promoting the ’24 Encore GX had the highest estimated spend ($6.3 million) of the top five, but the fewest airings (58) – all of which occurred during March Madness games (both men’s and women’s) and related coverage.
