TikTok is an iOS and Android social media video app for creating and sharing short lip-sync, comedy, and talent videos. The app was launched in 2017 by Chinese developer ByteDance, for markets outside of China. ByteDance, a Beijing-based company founded in 2012 by Zhang Yiming, had previously launched Douyin for the China market in September 2016. TikTok and Douyin are the same but run on different servers to comply with Chinese censorship restrictions. The application allows users to create short music and lip-sync videos of 3 to 15 seconds and short looping videos of 3 to 60 seconds. It is popular in Asia, the United States, and other parts of the world. TikTok is not available in China, and its servers are based in countries where the app is available.
