Last night (Tuesday, 17th April 2007) on SBS at 8:30 there was an excellent documentary on the phenomena of virtual worlds, such as Second Life, Entropia Universe and World of Warcraft, among others.
The doco focused on all the new enterprises that virtual worlds have spawned - Beyond the game developers. Enterprises such as Gold trading, Levelling and buying Virtual Real Estate, all undertaken with real cash.
The SMH has compiled a detailed brief review. If you missed it, I encourage you try to source it.
Some people may wonder what the fuss is all about, but consider this; by 2010 there will be over 12 million active Avatars!
At the moment there are about 6 million Avatars, which makes you think; if you are a Pepsi, Gillette, Absolut, Pizza Hut, etc, that perhaps you need to be developing an Avatar Marketing Strategy.
Coca-Cola thinks so.
