in reference to advertising & messengers, this is already being explored by many. Someone asked if it was faux pas for a messenger to wear an ad, the answer is Yes.

But only if there is no compensation. Taste is subjective.

Ads on messengers is a good concept, (except where all ads are evil of course!) and I've been toying with the idea (more than toying) as part of planned stop-gap against the current decline, until such time as the benefits of green delivery and other new markets are realized.

It's not my idea of course, the first I heard of it was some folk in Copenhagen, or Amsterdam many years ago. It's great from a visibility aspect. Most people when they hear about it think that since the messenger is riding around in heavy traffic all day that the people in the cars and on the sidewalks will see the ad and viola! you've reached a great many people! Not true. Drivers should be looking at the damn road IMO, and sidewalk folk could maybe pick up a very emblematic ad, or see it when the rider is stopped at an intersection, but mostly it would go by too quickly(although that too is kind of got cool appeal)

Most of your visibility is in elevators, escalators, lobbies, mailrooms, conference rooms, cube farms, hallways, bathrooms, waiting in line at the coffee joint, sitting around drinking the coffee, standing by waiting for calls on a street corner, you get it, pretty much freaking everywhere. People look at messengers, they can't help it, it's an incredibly small population, and different works in the ad world.

Some may see it as a sell out, but nobody is forcing them to wear an ad they don't like or agree with. IMO one should be paid for selling out, I'd rather have an ad I choose to have on my back that is there earning me $$ than branded crap that is there because the techwear I want is covered in doofus.
