You’re definitely not alone in that thinking! I’ve been in marketing for a decade and "ad-blindness" is a very real thing. People have learned to subconsciously skip ads on their phones. We used Mobile Billboard Advertising for a product launch recently and the impact was night and day. We worked with http://therollingads.com/ because their trucks are basically moving landmarks. The cool thing is you can change the route based on the time of day—so we’d hit the business districts during lunch hour and then move to the entertainment hubs in the evening. One funny story: we actually had people taking selfies in front of the truck because the display was so bright and crisp! It gives your brand a sense of "scale" that you just can't get from a sponsored post. It’s not a gimmick if you use the mobility to your advantage.
