WeChat is an instant messaging app developed by Tencent that has expanded to include various services such as social media, mobile games, and mobile payments. It has grown rapidly since its launch in 2011 and as of 2014 had over 400 million monthly active users. WeChat generates revenue through advertisements, mobile games, and its mobile payment system WeChat Pay. It has been very successful by offering a wide range of engaging features within its platform and through innovative marketing promotions. While facing competition from other messaging and social media apps as well as mobile payment services like Alipay, WeChat is predicted to continue growing its large, loyal user base and generating strong revenue due to its comprehensive, pervasive platform.
