Hmmmm. Playing games and watching tv is good for you. Well maybe. I played a lot of videogames, and I watched a lot of Spock on the TV, but I still failed my first college-level exam. "Learning" knowledge & "applying" knowledge are two different things. I knew a lot about pixels, sprites, and lightyears, but didn't know how to solve a simple "throw a ball in the air; how far does it travel?" physics problem. I still needed a teacher to guide me in how to get the correct answer.
I think it'd be more accurate to say games/shows/books can >complement< the classroom & homework, but not completely replace it.

Violence and sex you're worried about? Afraid it will warp the minds of your children? Ah, worry not, the content doesn't even matter! These things aren't out with a moral agenda! They teach you to think, which has nothing to do with morals at all. And don't forget, the most popular video game titles are the ones with almost no sex or violence.
It's just different kinds of smart. Even reality television, supposedly the lowest-of-the-low, can teach us important lessons and allows us to flex out social/emotional intelligence muscles.

Complicated television shows and movies, with more plot lines and characters than ever before tax our brains by making us memorize more complex social structures and sets of relationships.
Somehow he does an amazing job of factoring out everything else and makes an insanely plausible case. According to his studies, IQ scores have risen, on average, 13.8 points over the last 30 years, due almost entirely upon more complicated and interactive media forms.
So remember that television, movies, video games, and the internet make you smarter. Which means the next time one of those anti-TV people get in your face about the evils of television, you can kick them in the teeth.
