There is a fantastic and lengthy documentary series about the Civil Rights Movement called
Eyes on the Prize. I am lucky enough to have seen most of it during my public-school education. It's an amazing piece of work that drives home to "the kids today" just how different America was prior to the social upheaval of the 1960s, and how hard that entire fight was.
Alas, due to the way that our unbalanced system of copyright and "intellectual property" laws function, you pretty much can't see this amazing educational material anymore. And this isn't the only bit of our history that big corporations are walling off. There's more in a
great article at the Globe and Mail. The Washington Post has more, but they'll make you register to
read it.
