Second Life

Philip Rosedale formed Linden Lab in 1999 with the intention of developing computer hardware to allow people to become immersed in a virtual world. In its earliest form, the company struggled to produce a commercial version of the hardware, known as "The Rig", which in prototype form was seen as a clunky steel contraption with computer monitors worn on shoulders. That vision changed into the software application Linden World, in which people participated in task-based games and socializing in a three-dimensional online environment. That effort eventually transformed into the better-known, user-centered Second Life. Although he was familiar with the metaverse of Neal Stephenson's 1992 novel Snow Crash, Rosedale has said that his vision of virtual worlds predates that book, and that he conducted early virtual world experiments during his college years at the University of California, San Diego, where he studied physics.

Second Life began to receive significant media attention in 2005 and 2006, including a cover story in BusinessWeek magazine featuring the virtual world and Second Life avatar Anshe Chung. By that time, Anshe Chung had become Second Life's poster child and symbol for the economic opportunities that the virtual world offers to its residents. At the same time, the service saw a period of exponential growth of its user base.
