Cyworld is an Internet service that lets people create their own home page by providing unlimited photo uploading. About 15 million people, nearly one third of Koreans, are users of Cyworld. Amazingly, 90% of late teens and these in their early twenties are all big fans. Users own their own three-dimensional virtual rooms and individual avatars. Also, they can decorate their rooms with digital furniture, art, TVs, and even music. The service for using the site is totally free, but when users decorate their rooms with things, they need to spend real money.
