TikTok

TikTok (Chinese: 抖音; Dǒuyīn) is a Chinese video-sharing social networking service owned by ByteDance, a Beijing-based company founded in 2012 by Zhang Yiming. It is used to create short dance, lip-sync, comedy, and talent videos. The app was launched in 2017 for iOS and Android in markets outside of China. ByteDance first launched Douyin for the China market in September 2016. TikTok and Douyin are similar to each other and essentially the same app, however they run on separate 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. The app is popular in Asia, the United States, and other parts of the world. TikTok is available in China as Douyin; its servers are based in countries where the app is available.

TikTok was the most downloaded app in the US in October 2018, the first Chinese app to achieve this. As of 2018, it was available in over 150 markets and in 75 languages. In February 2019, TikTok, together with Douyin, hit one billion downloads globally, excluding Android installs in China. In 2019, TikTok was declared the 7th most downloaded mobile app of the decade, from 2010 to 2019.
