interrupt marketing

Interrupt marketing, sometimes referred to as interruption marketing, is the traditional model of product promotion, in which people have to stop what they're doing to pay attention  to the marketing message or deal with it in some other way. 

Examples of interrupt marketing include:

• Telemarketing calls.
• Mail campaigns.
• Email campaigns.
• Television and radio ads. 
• interstitial  and transitional online ads that interrupt or delay the user's selected content. 
• Pre-roll ads that play before video content. 

A newer approach, known as discoverability marketing, is based on presenting offers to people who are actively looking for similar products.
