The same might be said of the domestically underappreciated Google Orkut. Introduced in 2004 , the social networking site is a big hit in Brazil, but in the U.S., Orkut has lagged in popularity behind Facebook and MySpace. Google Orkut's lack of popularity in the U.S. has been attributed not only to strong competition from the other services, but also to such factors as its early "invite only" policy, a lack of support for blogging tools, and an absence of video features. http://www.businessweek.com/technology/content/oct2007/tc2007107_530965.htm
