This month the History Channel is rebroadcasting Band of Brothers, as well as a documentary by Tom Brokaw on 1968. (You can check your local listings at History.com.) Both look intriguing, and you can find study guides to these and many other programs here. Do be aware, however, that both of these programs are suitable for mature high school students.
You can sign up at History.com to receive e-mail updates on their programming, which will include links to their educational study guides.
