Musical.ly

Musical.ly (pronounced "musically", stylized as musical.ly) was a social media service headquartered in Shanghai, on which platform users created and shared short lip-sync videos. The first prototype was released in April 2014, and then after that, the official version was launched in August 2014. Through the app, users could create 15-second to 1-minute lip-syncing music videos and choose sound tracks to accompany, use different speed options (time-lapse, fast, normal, slow motion, and epic) and add pre-set filters and effects. The app also allowed users to browse popular "musers", content, trending songs, sounds and hashtags, and uniquely interact with their fans. In June 2016, Musical.ly had over 90 million registered users, up from 10 million a year earlier. By the end of May 2017, the app had reached over 200 million users. ByteDance Ltd. acquired Musical.ly Inc. on November 10, 2017 and merged it into TikTok on August 2, 2018. At the same time, Musical.ly Inc. changed its name to TikTok Inc.
