TikTok
TikTok, known in China as Douyin, is a short-form video hosting service owned by the Chinese company ByteDance. It hosts a variety of user-submitted videos, from content such as pranks, stunts, tricks, jokes and dance, with durations from 15 seconds to ten minutes. Both amateur and professional artists can cooperate on content and make split-screen duet videos even if they are in separate locations. They can also add effects like filters, background music, and stickers to their videos. TikTok is an international version of Douyin, which was released in the Chinese market in September 2016. It launched in 2017 for iOS and Android in most markets outside of mainland China; however, it became available worldwide only after merging with another Chinese social media service, Musical.ly, on 2 August 2018. TikTok and Douyin have almost the same user interface but no access to each other's content. Their servers are each based in the market where the respective app is available.
