Recently, Tencent introduced several new functions for its social platforms QQ and WeChat, including QQ Circle for organizing friends and WeChat's timeline feature. WeChat has also seen rapid growth, reaching over 200 million users through frequent app upgrades that enhance social and communication features. These upgrades allow sharing of photos, location-based services, and profiles. WeChat is becoming a widely-used cross-demographic social platform in China through its emphasis on mobile communication. Tencent aims to further develop social features for WeChat in 2013 to attract more brand marketing through the platform. Some companies have already begun using WeChat's API to power advanced location-based services and integrate WeChat with their CRM systems.
