Duff Energy Drink is made by Boston America. In an earlier post, I looked at Five Formerly Fictional Products , but there were bound to be more than five. Even though Groening decided not to license the Duff trademark for an actual beer— since it might be construed as promoting beer to children —the Duff logo has been licensed to a bunch of other products that are not beer and, in some cases, have very little to do with beer. The writers effectively depict Duff as a media-crazed beer company. These methods clearly appeal to the youth market, in which viewers with in the market are proved to be more susceptible to consistent drinking habits.
