Weibo (NASDAQ: WB) is a leading social media platform for people to create, distribute and discover Chinese-language content. By providing an unprecedented and simple way for Chinese people and organizations to publicly express themselves in real time, interact with others on a massive global platform and stay connected with the world, Weibo has had a profound social impact in China. Since our inception four years ago, Weibo has amassed a la…rge user base in China and in Chinese communities in more than 190 countries. In December 2013, Weibo had 129.1 million monthly active users, or MAUs, and 61.4 million average daily active users, or average DAUs, increasing from 96.7 million MAUs and 45.1 million average DAUs in December 2012, and 72.9 million MAUs and 25.2 million average DAUs in December 2011. In March 2014, Weibo had 143.8 million MAUs and 66.6 million average DAUs, increasing from 107.3 million MAUs and 48.6 million average DAUs in March 2013. A microcosm of Chinese society, Weibo has attracted a wide range of users, including ordinary people, celebrities and other public figures, as well as organizations such as media outlets, businesses, government agencies and charities. Weibo represents a new online experience in China by combining the means of real-time public self-expression with a powerful platform for social interaction, as well as content aggregation and distribution. Any user can create and post a feed of up to 140 Chinese characters and attach multimedia or long-form content. User relationships on Weibo may be asymmetric; any user can follow any other user and add comments to a feed while reposting. The simple, asymmetric and distributed nature of Weibo allows an original feed to become a live viral conversation stream. Over 2.8 billion feeds were shared on Weibo in December 2013, including 2.2 billion feeds with pictures, 81.7 million feeds with short videos and 21.5 million feeds with songs.
