I find that there's always something new to learn every day. Since somehow there isn't enough time in the day to fit everything in, I like that when I am learning something new - that it should come in small bites, easy and quick to read or watch.
Aish.com has a great collection of articles and videos covering Jewish history, ancient as well as modern day fitting my description. Definitely worth your time. Learning history is such an important thing to do - but too few people actually take any time to do it. We've got 3000 years of history behind us, take a moment to learn about some of it.
