A. Blizzard (World of Warcraft)

B. Linden Labs (Second Life)

C. Mattel (Hot Wheels, Barbie, etc.)



All right, so it's obviously C, otherwise why is this blogger jabbering at you, right?

Last night at the Digital Life preview a Mattel rep--who, just to make the conversation extra surreal, actually looked sort of like Barbie--told me that in the first 60 days of its existence, the new online virtual world Barbie Girls has signed up three million members, and they're adding new ones at the rate of 50,000 a day.

Just for reference, it took Second Life 3 years to reach 1 million members.
