Although virtual-world technology is in its developmental stage, its impact on societies and business operations is already evident. Last year, in Q4 alone, more than US $425 million had been invested in 15 virtual worlds; in Q1 2008, more than $184 million was invested in 23 companies. ¹ In addition, many children are being raised with broad access to virtual worlds. Indeed, they may spend more time watching TV, playing, socializing, and learning in a virtual world than in real life.
