Revenues from FinTech and Business Services increased by 39% year-on-year to RMB101.4 billion.

Social and others advertising revenues grew by 33% to RMB52,897 million.

Media advertising revenues decreased by 15% to RMB15,480 million. The decrease was primarily due to lower advertising revenues from our media platforms including Tencent Video and Tencent News resulting from unpredictability in broadcast schedules and the challenging macro-environment, as well as the absence of the FIFA World Cup in year 2019.
