To clarify a point from our business training:
PROMO LIT (Promotional Literature) is one of the ways in which marketeers can draw the attention of their target markets to the USPs of the goods or services they offer. Examples include:
HANDBILL – a small printed advertisement or notice distributed by hand
Synonyms: notice, advertisement, flyer, leaflet, circular, handout, bulletin, pamphlet)
FLYER – a form of paper advertisement intended for wide distribution and typically posted or distributed in a public place, handed out to individuals or sent through the post
LEAFLET – a printed sheet of paper containing information or advertising and usually distributed free (synonyms: pamphlet, booklet, brochure, handbill, circular, flyer, handout,
advertisement, bulletin, mailshot, bill, notice)
PAMPHLET – an unbound booklet (that is, without a hard cover or binding). It may consist of a single sheet of paper that is printed on both sides and folded in half, in thirds, or in fourths, called a leaflet, or it may consist of a few pages that are folded in half and saddle stapled at the crease to make a simple book
BROCHURE – a small book or magazine containing pictures and information about a product or service (synonyms: pamphlet, booklet, prospectus, catalogue, leaflet, handbill, handout, bill, circular, flyer, notice, advertisement)
CATALOGUE – a complete list of items, typically one in alphabetical or other systematic order
Note: USPs (Unique Selling Points) are the benefits particular to a specific product or service.
