"Media outlets have catered for a variety of audiences, and that fact that media messages are a marketable commodity has always meant that they reached out to as many people as possible. The competition between media companies, at least as far as newspaper and television stations was concerned, was therefore to capture a wide and numerous audience. The print media (newspaper, magazines and books) made more money for writers and organizations alike by selling many copies of their work, although even here the enormous importance of advertising (providing up to seventy per cent of revenue) has meant that the crucial factor for success is not so much how many readers but their social position. Thus, the "quality" of the media audience has always counted as much as its "quantity". Therefore, the media have aimed at particular, often the more affluent sectors of society."
