Zipping is the practice of viewers fast-forwarding through advertisements when watching a pre-recorded or leased videotape—is one of the most urgent issues facing television advertisers today.

According to research, there is a lot of zipping going on, which lowers the audience size for ads much below that for programming. Block zipping, which involves zipping two or more advertisements at once, was found to be the most common zipping activity.
