The widely popular app that is now know as TikTok, used to be called Musically. On November 9, 2017, Bytedance acquired the musically app and it was then set to merge with its Chinese counterpart Tik Tok, which also belongs to Bytedance.ByteDance decided to make a better app, so they merged TikTok content onto the global musically app and they rebranded it as TikTok. They renamed the app TikTok because musical.ly was always known for lip syncing, and they wanted a new name that would draw people to the app and represent the users of the app better. Most the famous people who got famous on musically continued to become famous on Tik Tok.
