Dear livejournal genie

For my intro class I am teaching a unit on advertising today. I know there must be a good short sci-fi story that deals with advertising. In fact, I remember reading one at some point, about a world so hypersaturated with advertisements that people have to pay a lot of money to be able to stay in a quiet room where there are no ads, and it becomes like an addiction...but I can't remember who wrote it. Does anyone know what I am talking about or have any other suggestions?
