QZone, second largest social network in the world (ranked according to userbase), is #4 brand.
Famous American brands are at the top 3: #1 Facebook with $34 billion, #2 Youtube with $27 B , #3 Twitter with $24 B.
Next brand in the list could surprise some people. With $10 billion, it is not SinaWeibo but TencentWeibo.
Next year we can expect the brand “WeChat” to enter the top 30 most valuable brands
