An essential tool of mass communication, newspapers, magazines, jornals and all other forms of published materials all constitute print media. Advertising in print media still has diverse effects on advertising and promotional activities. Print media advertising is a form of advertising that uses physically printed media tools. Advertisers in print media can buy different sizes of advertising space, from small classified ads with text only, to display ads featuring text, photographs, illustrations and graphics in sizes up to a full page or even a double-page spread. Print media advertising offers advertisers the opportunity to target different readerships, with advertising costs based on circulation and nature of the readership. Advertising on billboards and posters also gives advertisers the opportunity to reach consumers on the move.
