A captive advertiser refers to a company or individual who is contractually obligated to advertise a specific product or service. This type of advertiser is typically bound by a legal agreement or exclusive partnership, which restricts them from promoting any competing brands. This arrangement allows the advertiser to have a captive audience, as they have the sole opportunity to market their designated product or service to a specific target audience. Captive advertisers often have a strong influence on consumer behavior, as they have the ability to control the messaging and placement of their advertisements. This term is commonly used in the advertising industry to describe a strategic approach to marketing and branding.
