Are there any legitimate marketing studies or results that show that this technique is actually worth it? Everyone I know who I've ever asked just says basically, "Yeah, I know, I see them. They're amusing and a little annoying." I've never met a single person who was actually affected (or at least, who admitted to being affected) by these human advertisements.
Hence the question: is this actually worth the investment and having this person on payroll? Or is this a useless gesture that companies copy under the guise of "more exposure is better!!!!!!!!!11111" without any actual studies to back up this particular technique?
