BET, will have commercials with almost exclusively African Americans. The food commercials are stereotypical.

Country music channel, will have country looking people and Truck commercials.

Comedy Central, that appeals to everyone including You. You will see your stereotype played out in commercial. Things everyone gets, food, insurance, etc...

Text doesn't describe how stereotypical these commercials are. The subtle family structure, the restaurants/activities, the type of girl they use for a model.
