So an interesting thing about what nick.com is doing with Legend of Korra. They are only showing the episodes for a short while. After the release of the 8th episode, the first 2 episodes disappeared. This means that that only 6 episodes are currently available.
This makes sense though, when you look at their business model. The goal is to give dedicated viewers free streaming video, while allowing those coming later, to buy the videos from Amazon.com or iTunes (though not from Google Play). I'm all for people watching these video's legally, which is why when I saw that the first 2 episodes disappeared, I immediately wanted to direct people to the cheapest alternatives.
iTunes and Amazon.com have the shows in HD for $2.99 each. iTunes as a bonus has episodes 1&2 together for $4.99 (a $1 savings). Furthermore, Amazon.com has the shows in Standard Format for $1.99 each.
Amazon.com also gives you their TV pass. TV pass is essentially a subscription for the season. You pay for each episode at a reduced price, and are charged the reduced price as the show is made available. You get to keep all episodes purchased this way as well.
I still wish they would make it available for Hulu Plus or Netflix subscribers (the way Phineas & Ferb are available to Netflix for example). But just because its not, does not mean you should pirate the videos. It's only $2! So please, if you want to watch the first 2 episodes, go to Amazon.com and download them for $4 (or if you want them in HD get both from iTunes for $5).
Continued support of online distribution methods is the only way we'll see other shows (like Game of Thrones, which is only available if you also have HBO on your cable/satellite subscription) made available to us. Thank you for your time.
