Program interrupters are a type of advertisement or sponsor that interrupts a program or show in order to promote a product or service. ADS and SPONSORS are two common types of program interrupters. ADS are short, three-letter advertisements that appear during a program or show, while SPONSORS are longer, eight-letter advertisements that are usually placed at the beginning or end of a program or show. Program interrupters are used to increase brand awareness and generate revenue for the program or show.
