Truck advertising is a type of mobile advertising. What is mobile advertising you asked? It's simply an out-of-home advertising that moves. Out-of-home advertising is initially a very good way of doing advertising if you want your message to reach as many people as possible. With thousands of people passing by your ad everyday, you are sure to make a great number of impressions. But what about the other way around? Your ad passing by people instead of them passing by your ad, meaning mobile advertising. Cool, eh?
