Add your business.. advertising, in general, any openly sponsored offering of goods, services, or ideas through any medium of public communication. At its inception advertising was merely an announcement; for example, entrepreneurs in ancient Egypt used criers to announce ship and cargo arrivals. The invention of printing, however, may be said to have ushered in modern advertising. After the influence of salesmanship began to insert itself into public notice in the 18th cent., the present elaborate form of advertising began to evolve. The advertising agency, working on a commission basis, has been chiefly responsible for this evolution. The largest group of advertisers are the food marketers, followed by marketers of drugs and cosmetics, soaps, automobiles, tobacco, appliances, and oil products.
