More on virtual world growth

Heard of Spineworld? I hadn't. But a 10-year-old I know told me he's seeing it everywhere in his circles. Now we know from UK-based market researcher K Zero that its population (registered users) has more than doubled since first quarter '09, from 1 million then to 2.8 million now, according to VirtualWorldsNews. Overall, "the total number of registered accounts in the virtual worlds sector totaled 579,000,000 in the April-June quarter, 2009. That's an increase of 38.6% from the prior quarter when the tally was 417,000,000." K Zero adds that 60% of all virtual world users are between the ages of 10 and 15, "followed closely" by 5-to-10-year-olds, reports in its 2nd-quarter '09 update The problem is, its eye-grabbing chart is pretty imprecise, making it appear that more than 75% of the total VW population are 10-15 years old and that 5-to-9-year-olds represent about a quarter, with nothing left over at all for users 16+. As for individual kid worlds, besides Spineworld's, some of the biggest gains were seen by Stardoll, which added 8 million users; Club Penguin (6 million); Nicktropolis (3.1 million); and UK-based Moshi Monsters (3 million). The reports says Poptropica gained 36 million users, but that must be a typo, right? [See also "Undercover Mom in Poptropica" and in Stardoll, and our complete Undercover Mom series.]
