push advertising

Push advertising is the traditional marketing approach, in which promotional material is presented to large groups of people through channels including flyers, magazines, television, radio and billboards. Online examples of push advertising include email campaigns, interstitials, pre-roll video ads and banner ads.  Push advertising is often interruption marketing, meaning that the prospective customer has to stop what they're doing to deal with the message in some way. 

The push marketing model contrasts with pull marketing, an approach designed to draw customers to a brand through search engine optimization (SEO) and other non-intrusive methods.
