Perhaps the most obvious kind of commercial art is advertising. More commercial artists work in the advertising industry than in any other.
Advertising can take the form of billboards, posters, pages or parts of pages printed in magazines and newspapers, and television commercials. Advertisements, or ads, tell people about new products or remind them to buy old ones. They publicize everything from automobiles, washing machines, and perfume to plays, movies, television programs, and books. At election time even political candidates try to "sell themselves," and ads give voters information about candidates' positions on various political issues.
Some advertising is called public service advertising. Instead of trying to sell a product, it delivers a message that is beneficial to the community in which it appears. It may remind people not to litter, caution them to fasten their seatbelts, or warn them not to drink and drive or take drugs.
