Second Life (SL) is a virtual world in which most (around 90%) content is user-created. Second Life was created by Linden Lab (LL) in 2002, first bearing the name "Linden World", then later renamed to "Second Life" and opened to the public in 2003. While SL is not the first virtual world of its kind, it has broken new ground in many ways. One of the most often talked about aspects of Second Life is the fact that users own the intellectual property of their creations in the world. This allows the user to create something in SL and then later "export" it to another medium and still maintain ownership of that creation. An example of this is Tringo.
