Netflix uses a variety of data analysis and inference methods to provide users with suggestions but also for their own corporate usage. While it is a year old, this Wired article sums the process up with reasonable comprehensibility. My Netflix profile indicates that my "taste preference" is "Critically Acclaimed, Witty, Visually Striking Movies." And somehow, that category includes: Wallace & Gromit: Curse of the Were-Rabbit, something called Sita Sings the Blues, six French films, one Italian film, the oft (should be off-ed because it's been so over-) quoted Monty Python and the Holy Grail, two Wes Anderson films, a Woody Allen film, and The Graduate.
Also, my top picks include, Murder She Wrote, Columbo, From Russia with Love, Pokemon (!?!?!?), The A Team, Ghostbusters, Patriot Games, My Little Pony, and Top Gear.
This all leads to a very sensible question: What the hell have I been watching? And really, Pokemon and My Little Pony? Horrible. Now, if you'll excuse me, I have an episode of Mork and Mindy to finish.
