Tag-on
Also called: reminder
A tag-on or reminder is a very short commercial that airs on radio or television shortly after the main spot has been aired. The purpose of a tag-on is to grab the viewer's or listener's attention again within the same commercial break. Often the payoff or a call-to-action are repeated. Sometimes a tag-on is also used to communicate a special offer.
Research has shown that combining commercials with a tag-on increases the effect of rtv advertising. During a campaign, tag-on content can be alternated.
