Second Life is the leading 3D virtual world filled with user-created content and immersive experiences.
In Second Life, Residents meet and interact with friends around the world, enjoy entertainment from live music to role-playing games, explore unique environments and communities, and much more. Residents can also create, buy, and sell anything they can imagine, participating in the world's largest user-generated virtual goods economy.
Today, Second Life's virtual land mass would be roughly twice the size of Hong Kong. In Q3 2010 alone, over 750,000 unique Residents from around the globe spent more than 105 million hours experiencing Second Life while exchanging more than $150 million worth of Linden dollars in its economy.
