TikTok’s rise has been meteoric. The fast-growing platform, simply described as an app for posting and sharing short videos, has been downloaded more than 1.65 billion times globally since 2016 and currently has more than 800 million monthly active users. Some industry leaders speculate that it could eclipse Instagram. When it comes to total cumulative users, ByteDance, the Chinese company behind TikTok, now ranks third, behind Facebook and the Chinese multinational Tencent (which owns WeChat, China’s largest platform, and QQ). With a valuation of US$75 billion, ByteDance is also the world’s most valuable start-up.
