Internet Movie DataBase (Internet, WWW, DB)
"Instead of asking you to input ratings or to tell it what movies you like, IMDb automatically recommends similar films to the movie you search for. At the bottom of the page, a "Recommendations" section explains that if you liked a respective film, you'll like the handful of other films being displayed, based on information gathered from an IMDb database, which examines films to find similarities and differences. It's a great way for people who don't have time to rate movies to find some films worth watching. Even better, the recommendations are solid."
