TikTok, known in China as Douyin, is a Chinese video-sharing social networking service owned by ByteDance, a Beijing-based Internet technology company founded in 2012 by Zhang Yiming. It is used to create short music, lip-sync, dance, comedy and talent videos of 3 to 15 seconds, and short looping videos of 3 to 60 seconds.
ByteDance first launched Douyin for the Chinese market in September 2016. Later, TikTok was launched in 2017 for iOS and Android in most markets outside of mainland China; however, it only became available worldwide, including the United States, after merging with another Chinese social media service Musical.ly on 2 August 2018.
