Advertising agencies like to schedule their commercials in television shows that appeal to the 18-49 demographic, because this segment of the population has a lot of spending power.
Demographic is a word companies use when they're trying to sell their products to a particular group of consumers. A movie studio that wants to promote its new film, “Revenge of the Senior Kitties,” might aim for the 65-to-85-year-old cat-lover . A demographic can consist of people who are in the same age group, such as 18-to-29-year-olds, or ethnic group, such as African-Americans.
