In 2001 Robert Heath stirred up the advertising world with The Hidden Power of Advertising, an Admap monograph outlining a Low Involvement Processing (LIP) model of how consumers process advertising. His claims were robustly challenged, not least from those who sought to promote TV advertising as a ‘high involvement processing’ model which sought, and obtained, the active attention of consumers.
Although Heath’s paper was published only 11 years ago, it was a time when advertising was operating in a very different landscape, in terms of media channels and content, and how consumers make use of that media. Digital TV was in its infancy, fewer homes had multi-channel, broadband had yet to be rolled out, and smartphones, in any real sense, were still a thing of the future.
