Tencent's WeChat surpassed 300 million users on Jan. 15, less than two years after its launch on Jan 21. 2011. 

Over the past year, WeChat saw growth accelerate. In March 2012, the company reached 100 million users. Six months later on Sept. 17, the company reached 200 million users. In the five months since, WeChat added another 100 million users, with international exposure in Hong Kong, Taiwan, Macau, Japan, and the United States.

WeChat is a mobile communication application that allows users to chat one-on-one and in-groups. Available on iOS, Android, Windows Phone, and BlackBerry, the service lets you find new chat friends based on location, as well as snap and filter photographs. Users can also communicate to each other across platforms and on the PC.

Tencent will continue to expand WeChat abroad. It plans to build data centers in the United States, Southeast Asia, and elsewhere to speed up the user experience.
