Bus Shelters. Bus shelter panels offer uncluttered showcases for advertising, mounted (usually two per shelter) in glass, backlit frames. They provide 24 hour visibility to vehicular and pedestrian traffic at high-circulation locations, usually along main roadways of metropolitan markets. It helps to spread awareness about products or services that are of some use to consumer and potential buyers. The main aim of advertising, many believe is to sell. … Advertising on the whole helps business as well as the economy to prosper and makes the consumer aware of the various choices that are available to him. If Westar Energy is the only electric company that serves my area, then why spend any money advertising? Most companies market for competitive reasons – to persuade you to buy their brand or to do business with them. But that isn’t why we advertise. At Westar Energy, we advertise not to compete, but to communicate.
