    WeChat, the Chinese social media smartphone app, saw an increase in user numbers of 41 percent year on year to 500 million at the end of last year, in a sign that parent company Tencent is extending its reach for the mobile Internet. As one of the largest Internet integrated service providers in China and one of the most Internet users in China, Tencent’s profit grew 24 percent to RMB 20.98 billion per year, slightly higher than forecasts, driven mainly by online gaming profits. It is unclear how much WeChat contributed to Tencent’s profits but the app’s growth is a strong indicator of the company’s long-term health as it tries to adjust its business to be more suitable for mobile devices.

“We extended our leadership in games and online media, and made breakthroughs in emerging platforms such as online security and mobile payments.” Ma Huateng, Tencent chairman, said in a statement. WeChat is the second highest ranked social app in China, behind QQ, Tencent’s another chatting app, which claimed to have 815 million registered monthly users at the end of 2014.

Tencent has been unwilling to earn money through WeChat by flooding it with advertising, which could influence the users’ experience. But this is expected to change. Some analysts anticipated(预期) that advertising would be introduced on a large scale later this year. Early attempts to test ads on the service have not always gone smoothly. After a BMW ad was introduced on some users’ feedbacks in January, many users who were not targeted by the brand’s marketing complained of “discrimination” by Tencent’s data mining algorithm(数据挖掘算法). They claimed it unfairly treated them as not wealthy or successful enough to view the BMW ad.
