I think it's the changing of the times. Way too many distractions for kids these days. When I was young, I remember pouring over books, studying pictures, even if I'd already looked at them a hundred times. Now, there's more to pull kids away.
If I use my son as an example, in his room alone he has: satellite TV, wireless-enabled PC, a DVD player, as well as his toys and Nintendo DS handheld, an acoustic guitar, electric guitar, stereo, and banjo...

Seeing how my neices are when they visit, they're badgering us to us the computer and talk to their friends over AIM. And I'm sure they aren't talking history (unless who broke up with who yesterday is considered history these days)....
