Figure. (Right) VPRO's 24hr Cinema Service is an online movie database, connected to a database with information about TV programs in the Netherlands. Based on personal ratings of movies, users can get weekly email messages that inform them about movies on television that they might like. This screenshot shows basic information about The Shining and also shows a list of 'related films'. That list is solely based on user ratings: "if you like The Shining, you may also like Dead Calm, or The Mission, or Twin Peaks, etc."
