Promotional merchandise are products branded with a logo or slogan and distributed at little or no cost to promote a brand, corporate identity, or event. Such products, which are often informally called promo products, swag (mass nouns), tchotchkes, or freebies (count nouns), are used in marketing and sales. They are given away or sold at a loss to promote a company, , brand, or event. They are often distributed as handouts at trade shows, at conferences, on sales calls (that is, visits to companies that are purchasing or might purchase), and as bonus items in shipped orders. They are often used in guerrilla marketing campaigns. The first known promotional products in the United States were commemorative buttons dating back to the election of George Washington in 1789. During the early 19th century, there were some advertising calendars, rulers, and wooden specialties, but there was no organized industry for the creation and distribution of promotional items until later in the 19th century. Jasper Meek, a printer in Coshocton, Ohio, is considered by many to be the originator of the industry when he convinced a local shoe store to supply book bags imprinted with the store name to local schools. Henry Beach, another Coshocton printer and a competitor of Meek, picked up on the idea, and soon the two men were selling and printing marble bags, buggy whips, card cases, fans, calendars, cloth caps, aprons, and even hats for horses. In 1904, 12 manufacturers of promotional items got together to found the first trade association for the industry. That organization is now known as the Promotional Products Association International or PPAI, which currently has more than 10,000 global members. PPAI represents the promotional products industry of more than 22,000 distributors and approximately 4,800 manufacturers. The UK and Ireland promotional merchandise industry formally emerged as corporate marketing became more sophisticated during the late 1950s. Before this, companies may have provided occasional gifts, but there was no recognised promotional merchandise industry.
