A new book came out, the current headlines are "Watching TV makes you smarter" but I guess, according to the author of the book, the book focuses more on games rather than TV. It's just that more people watch TV so making a issue out of that he hopes will get more people interested in the book.
As small excerpt:
"Imagine an alternate world identical to ours save one techno-historical change: videogames were invented and popularized before books.

What would the teachers, and the parents, and the cultural authorities have to say about this frenzy of reading? I suspect it would sound something like this:

Basically I think he is arguing that the judgement of whether or not a certain entertainment is good or bad for you is normally about if the material is "smart" (Frasier vs Full House) but that instead it should be about how much it makes you use your brain (Frasier vs 24 vs games).

Games usually take that even further. It's an interesting idea.
