According to Johnson popular culture has grown more complex and challenging over the years. Is this true? Generally, I would agree. The situations presented through the new games, television, and other medias are presented for the same basic reasons. Johnson mentions "dopamine" and "brain chemistry," and yes, it can be reasoned that the basic premise individuals participate in these activities are still to feed those needs.
However, the level of sophistication (and that's not necessarily used in a good sense) of these medias is higher and increasingly complex. Certainly comparing the storylines of tv shows of the past and present show an elevated height of entanglement, but if you boil it down to the basic level, the morals and lessons are similar. The difference is that our medical and legal shows bury themselves in technical terms in order give themselves credibility which translates into ratings.
Social networking is another area in which we can ask the question, "is bad good?" It depends on who you ask and their ability to see this in it's entirety. Without a doubt, a teenager will tell you the many advantages. You might even have 30 year old's telling you it is a great way to save on phone bills - it's the ability to stay in touch and connect with people all over for the cost of basic internet service (which is now fairly common). However, ask the parent of a teenager who has been engaged in an online chat room by a stranger, and you may get a totally different response.
There is some truth that "popular culture is just a method to sophisticatedly deliver stupidity." Isn't it stupid to display all of your personal information on a site where it can be accessed by people you don't know? Isn't it stupid to watch a "sophisticated" sitcom about housewives when you could be reading a book? Isn't it stupid to be playing a video game when you could be outside throwing a ball and teaching your child how to catch, run and live a healthy lifestyle?
Alas, there's no right answer to any of this. It's all a matter of opinion and perspective.
