Those inquisitive little bloggers over at Google Operating System: Unofficial News and Tips About Google turned me on to Google Now. Visit https://www.google.com/now/topics/ and you’ll find a graphical list of topics that you searched in the past week and the past month.
It only picks up terms you searched on multiple occasions and it appears to only collect what you searched when you were logged in to your Google account.
Last week, I was looking up the movie The Internship and that led to this box. In Google’s mind, if I like The Internship, I’ll also enjoy Jurassic Park, Lincoln, Schindler’s List and ET. That’s one of the most mismatched collections of movies I’ve ever seen.
