Watch Mojo has produced eight good "decade in review" videos covering a variety of topics. The topics in the Watch Mojo "decade in review" playlist include politics, science & space, and entertainment. I've embedded the politics video below.
While these videos are good, I encourage you to use a service like Quietube for displaying them in your classroom as some of the other videos produced by Watch Mojo push the limits of PG-13.

There are many "decade in review" videos floating around the Internet right now. It's interesting to note what video producers do or do not include in their recaps of the decade. As an activity in media literacy you could have students watch a few different videos and then discuss why a producer would include certain events while leaving out other events.
