Draftback is a Chrome extension that allows you to look at the revision history of a Google Doc as a video. Once you add it to your Chrome browser, you'll see a new choice at the top of your Doc.
Click "Draftback" (inside the parenthesis is the number of revisions).
Once it renders the video, click "View."
