I just read Victor Keegan's article at The Guardian 'Virtual worlds are getting a second life' quoting a Kzaro report that membership of virtual worlds grew by 39 % in the second quarter 2009 to about 580 million people and while 'Facebook and Twitter Make Noise, virtual worlds like WoW, Second Life Make Money'
So I wanted to know more about what KZERO [the self proclaimed Resident experts in virtual worlds] does, what Kzaro offers and found a lot of interesting research and services. Among them this nice graphs, which tell that youngster (still) love Virtual Worlds and Reality and spend money [buy subscriptons] for it.
and youngsters and people young at heart have wide and growing area of interest they spend time and money on in VR's
I bookmarked the Kzero page for keeping myself appressed on Virtual World's Business.
