Carmakers whose ads reached the most American buyers in late summer were Honda, Toyota, and Nissan; the Japanese reached on average 22% more
audience than U.S. automakers and 27% more than European manufacturers. Among the findings of the study, based on the number of times car ads were seen by consumers in New York, Houston, Denver,
Chicago, Los Angeles and Miami: The automaker with the greatest number of overall net impressions on radio and TV was Honda, with 28% more reach than the average of all the other automakers; Mazda had
the most television net impressions at 37% above the average, while BMW was an overwhelming leader in radio with 239% more.
But when it came to effectively using a cross-platform strategy, Ford had the biggest percentage increase in overall unique audience -- 37% -- when adding a second medium: radio.
