Nothing to do with technology, but still an idea: advertising agency that connects car owners that are willing to lease their cars’ outer space for ads, and advertisers. Ad-placement on buses is very popular, so why not on cars?
Several issues worth noticing:
1. Payment model. The payment to car owners should be per km. The longer one drives, the more exposure the ad on his car gets – so the compensation should be proportional to number of kilometers the driver makes.
2. Routes attraction. Some routes may be more attractive to advertisers than other. Someone that drives through lonely deserted roads shouldn’t be compensated as much as someone that drives through the busy parts of the city. The tricky part is how you monitor that.
3. Local vs. National. Town folks that live in a city, and rarely leave it are suitable to carry local-targeted ads, whereas people that live in the suburbs and drive to work in large city are more suitable to carry more general ads.
4. Car image. Not all car models are suitable for all kinds of ads. Fiat Uno 1980 model might not be the best choice to advertise a luxury hotel.
5. Dissemination. This advertising model’s biggest attraction is the ability to disseminate a message. Like ants in an anthill, cars swirl around the city, and carry little pieces of advertising messages. It allows advertisers to break their message in many little sub-messages and create effective teasing campaigns.
Anyway, that was just another idea to put in the trash bin.
