The review should take note of the overall target market. However, this does not necessarily mean that the advertising campaign will be directed at the total target market. Marketers and advertisers make a distinction between the "target audience" for an advertising message and the "target market" for a product or brand. By definition, the target audience is the intended audience for a given advertisement or message in a publication or broadcast medium, while the target market consists of all existing and potential consumers of a product, service or brand. Companies often develop different advertising messages and media strategies to reach different target audiences. For example, McDonald's Restaurants uses the anthropomorphic brand characters, Ronald McDonald and Hamburgler, in its advertising directed at children who are important brand-choice influencers. However, for adult target audience members, McDonald's uses messages that emphasise convenience and quality. Thus the target audience for a given advertising message may comprise only a subset of the total market as defined in the marketing plan. Careful perusal of the marketing plan will assist marketers in the process of defining the optimal target audiences for specific advertising objectives.
