A decade is a long time for anything to last. Most things start to fade at the 4 year mark. While not completely forgetting these things do tend to wane in popularity. Therefore for World of Warcraft to still have 7.4 million subscribers (source) after 10 years is pretty amazing. In order celebrate this a new documentary called "World of Warcraft: Looking for Group Documentary" was recently released. Here they talk about the inception of MMO's that spawned the idea of WoW, the pitfalls they ran into, and what they do to try and please the players. It is just over an hour, but is pretty entertaining.
