Another example of reinforcement advertising is the “surround session”, introduced by the online unit of the New York Times. This model emphasises on the interaction between advertisers and audiences. In such a session, an advertiser has all or most of the advertisements on each page for a surfer’s entire site visit. As the surfer moves from one page to another, the same advertiser is represented in various ad placements. This allows for reinforcement of the advertiser’s message.
