You can now legitimately watch all of the South Park episodes online for free - from the official South Park Studies website. All of the episodes are available on demand, and all of the partial-clips are available for sharing. For South Park fans, people who want to get into the show, or if you missed an episode that everyone is talking about, this is a great deal. This type of back-log archiving is what all studios should be doing - it's the easiest way to help prevent people turning to Bittorrent, and it won't stop the people who want DVDs from purchasing them. It all comes down to what's easiest for consumers, and creating an easier option that you can monetize is just smart business.
