Advertising is just one of many elements that comprise the promotional mix. When marketers communicate with target markets across a broad range of different promotional types and media, the potential for contradictory or mixed messages is very real. Accordingly, it is important that advertising is treated as part of a total marketing communications program and that steps are taken to ensure that it is integrated with all other marketing communications, so that all communications messages speak with a 'single voice'. The process of ensuring message consistency across the entire marketing communications program is known as "integrated marketing communications".
