How Do TV Commercials Influence American Culture?

Today I read an article with my class written by Garth Sundem, called ''How do TV Commercials Influence American culture?''.  This article was a real eye widener for me as I failed to realise how much influential advertisements can really be. 

When reading, I found if it makes the viewer look cooler, better looking or bring back a positive thought or memory, they would most likely buy the item. One of the many amazing thoughts Garth Sundem had was how most TV commercials were idealised.  As in perfect.
