Second Life is an online virtual world, developed by Linden Lab, based in San Francisco, and launched on June 23, 2003. By 2013 Second Life had approximately 1 million regular users, according to Linden Lab, which owns Second Life. In many ways, Second Life is similar to MMORPGs (Massively Multiplayer Online Role Playing Games); however, Linden Lab is emphatic that their creation is not a game: "There is no manufactured conflict, no set objective".
