Bus advertising uniquely reaches those in their cars and those walking on the sidewalks. The height of typically-sized advertising on buses is at the ideal viewing height for the drivers sitting in their cars and the passersby alike.
This is similar to how those confuse the target audience for bus shelter advertising, which reaches pedestrians and passing vehicles rather than those waiting for the bus, necessarily.
Bus interior advertising, also called bus interior car cards, effectively reaches those riding on the bus. Heck, no one wants to look at each other anymore!! Most passengers either look down at our phones or up at the bus interior ads.
The advertising on the interior of buses most typically targets lower income individuals and one will often see ads for bankruptcy attorneys, payday loans and other predatory models that serve the low income community.
