Promotional Representatives, also known as promo reps, are people who are hired to promote a brand, product, or service. They are generally hired by event marketing agencies, staffing agencies, and companies choosing to promote their products, services, and brands through the use of live events, mobile tours, and guerrilla marketing instead of television, radio, and print advertising.

Promotional products, also known as ad specialties, make up a 19.4 billion dollar industry and are used by virtually every business in America. Items like mugs, t-shirts, and pens are memorable and create a low cost per impression. [1]
