Some products require customers be exposed to just a little bit of information in order to build customer interest. For example, the features and benefits of a new snack food can be explained in a short period of time using television or radio commercials. However, complicated products need to present more information for customers to fully understand the product. Consequently, advertisers of these products will seek media formats that allot more time to deliver the message.
Media outlets vary in how much exposure they offer to their audience. Magazines and other publications provide opportunities for longer exposure times since these media types can be retained by the audience (i.e., keep old magazines) while exposure on television and radio are generally limited to the time the ad was broadcast.
