Foremost among marketing’s many responsibilities is filling the sales funnel with new prospects. Historically, this meant brands needed to insert their brand’s message in front of as many potential customers as possible, as often as possible. Ultimately, this gave rise to a number of advertising formats like print, TV, radio, outdoor, direct mail, and internet banners. Whatever a person enjoyed spending time doing, an ad could and would interrupt the experience essentially forcing the prospect to shut up and listen. Thus, the term Interruption Marketing.
