In entertainment, a tagline (alternatively spelled tag line) is a short text which serves to clarify a thought for, or is designed with a form of, dramatic effect. Many tagline slogans are reiterated phrases associated with an individual, social group, or product. As a variant of a branding slogan, taglines can be used in marketing materials and advertising.
The idea behind the concept is to create a memorable dramatic phrase that will sum up the tone and premise of an audio/visual product, or to reinforce and strengthen the audience's memory of a literary product. Some taglines are successful enough to warrant inclusion in popular culture. Consulting companies which specialize in creating taglines may be hired to create a tagline for a brand or product.
Tagline, tag line, and tag are American terms. In the U.K. they are called end lines, endlines, or straplines. In Belgium they are called baselines. In France they are signatures. In Germany they are claims. In the Netherlands and Italy, they are pay offs or pay-off.
Referral networking organizations may encourage taglines to be used as the conclusion to an introduction by each attendee. The purpose would be to make the introduction and that speaker more memorable in the minds of the other attendees after the meeting is over. Other terms for taglines are "memory hooks" (used by BNI®) and "USP" or "Unique Selling Proposition" which is a more commonly known term.
