Promotional items or promotional proucts refers to articles of merchandise that are used in marketing and communication programs. These items are usually imprinted with a company's name, logo or slogan, and given away at trade shows, conferences, and as part of guerilla marketing campaigns. These items are also referred to by the slang terms swag (probably from the British usage of the word meaning "stolen goods" or "loot"), or tchotchke (derived from a Yiddish word meaning "trinket").
