A promotional model is a model hired to drive consumer demand for a product, service, brand, or concept by directly interacting with potential customers. Most promotional models are conventionally attractive in physical appearance. They serve to make a product or service more appealing, and can provide information to journalists and consumers at trade shows and convention events. Promotional models are used in motorsports, other sports (such as dart competitions) or at trade shows, or they can act as "spokesmodels" to promote a specific brand or product in advertisements.
