Second Life

Second Life (SL) is a virtual world developed by Linden Labs launched on June 23, 2003, and is accessible on over the internet. A free client program called the Viewer enables its users, called Residents, to interact with each other through 3D avatars. Residents can explore, meet other residents, socialize, participate in individual and group activities, and create and trade virtual property and services with one another, or travel throughout the world, which residents frequently refer to as "the grid".
