Only a few other virtual worlds allow avatars to create and sell content as Second Life does. But users are flocking to the other worlds, in part because some don't require people to download software to take up residence.
Others just want to access a larger community than Second Life offers. Between May and June, the population of active avatars declined 2.5%, and the volume of U.S. money exchanged within the world fell from a high of $7.3 million in March to $6.8 million in June.
Companies are following them. IBM Corp., which has an extensive presence in Second Life, is expanding into the other environments, including There, which features a digital version of the popular TV show "Laguna Beach," and Entropia Universe, which pits users against one another in a sci-fi civilization.
Consulting firms that were set up to bring brands into Second Life are busy helping clients explore other worlds.
One such agency, Millions of Us, recently announced that it had formed a partnership with Gaia Online, a site popular with teenagers, and CEO Reuben Steiger said it would be unveiling more soon. Millions of Us had previously worked only with Second Life.
"It's not about whether Second Life is good or bad," Steiger said. "It's just that there are a lot of alternatives."
