My boys (9 and 7) were watching SML or "SuperMarioLogan" starring a vulgar retarded puppet, Jeffy. Stupid-funny and very politically incorrect, I still make them turn it off (though I'm sure they watch it when I'm not around).
Point is, there is an entire generation being reared that watches nothing on TV or cable. My boys watch YouTube videos made by teenagers or 20-somethings, at home with iPhones and puppets.
That's gotta make Disney and Nickelodeon nervous.
Things ARE changing. My 7 year old doesn’t have any interest in Star Wars at all, and yes, basically watches how to videos (lego building) on youtube.
