Sina Weibo Reaches 400 Million Users

Sina Weibo Tops 400 Million UsersChina’s Twitter-like Sina Weibo has topped 400 million registered users, according to the Q3 financials for Chinese web portal Sina.  This growth is largely being attributed to this summer’s Olympic games: Chairman and CEO Charles Chao said “The London 2012 Olympic Games could very well be termed in China as the ‘social’ Olympics, pushing Weibo.com’s daily active users to a new record.”

Back in August 2011, Sina Weibo had just 200 million registered users; this number grew to 300 million by May of 2012.  While last quarter Sina Weibo reported 36.5 million average daily active users, there was no mention of that statistic in this quarter’s report.

Noting that Weibo is not bringing much in terms of profit to Sina, Steven Millward at Yahoo News also makes an interesting point about how much censorship must cost the company.  “As China’s top social media service, it’s under huge pressure from authorities to implement all the same monitoring and censorship as any media company – but Sina must do it in real-time with tens of millions (or sometimes hundreds of millions) of daily active users.”
