Essential Question Post #7

This past weekend while I was watching a movie with some of my friends at my house, an new essential question came to my mind. The movie was Josie and The Pussycats. In the movie, Josie and the Pussycants become famous because they are picked up by a producer who doenst really nead a good band but any band because they play subliminal messages in the music which cause the people that listen to the music to like or buy whatever the subliminal messages tell them to like or buy. So basically that music company controls all of the fads, and what everybody should buy, wear, eat, and say. Everytime they make a new song, they could make new fads. This helped all of the merchandising companies, and a lot of manufacturers made a lot more money because of this music buisness. This made me start to think about fads in general. Even though in real life, there aren't any subliminal messages in music telling us what all the new fads are, we seem to have new ones popping up almost every week. Basically my new question is: Why do people feel the need to always buy the newest, best, "in" thing? Why are there always so many fads, and why do so many people follow them?
