Douyin (also known as TikTok) is a Chinese short-video-sharing app that was first launched in China in September 2016. The app allows users to create and share 15-second videos set to music and other audio and visual effects. After its launch, the app quickly gained popularity among young users. The app’s success in China led to the development of a global version, TikTok, which launched in September 2017 and is now available in multiple languages in over 150 markets worldwide. Douyin’s active user base is growing quickly and steadily. It is expected to exceed 800 million users by 2025.
