Comment about "The Merchant of Cool"

In the video of the "The Merchant of Cool" I learned that media fashions are very attractive to teens. Teens follow whatever is on the show,they spend money on the things that they don't need. Nowadays, teens are running the economy. They get money from their parents because their parents don't have time to spend with them. With all the extra money that the teens own, they can spend on everything that they like. This give the merchants ideas by promoting more commercials on TV Channels. They find celebrities to represent their products, telling teens that buy it, try it; this XX celebrity is using it. And teens that want to stay cool have to change right away. The faster the trends spread, the faster people focus on that specific products, the more moneys media companies receive.
