Advertising is to tell other people that you have something you want to sell them. When we say today that advertises, means that he is paying someone else to publish (that is, “to make public”) the information he has something to sell. There are many ways that this information may be made public. Different ways are called the media of human advertising. This can be printed notice (“Ads”) in newspapers and magazines; or spoken announcements (“ads”) to radio and television broadcasting; or displays, such as billboards, electric signs, and posters; or direct mail, which means mailing a letter to the person you want to sell; or souvenirs, such as matchbooks or calendars with the name of the advertiser on them; and many other media all the way up to skywriting.
Advertising is big business in the United States. In a typical year, 1950, American businessman was more than 7 billion dollars advertising things they had for sale. The largest part of this-more than a third was devoted to the “space” in the newspapers. Another third of 7 billion dollars was part of both the television, radio and magazines. This means that each of these media had about 10% of all the money that was spent. Direct mail accounted for about 15%. The rest of the advertising money was divided among many other media. Advertising is also an art. The best writers and artists combine their skills
