Kevin Mayer, who ran the video streaming business at Disney, will however start serving as the chief operating officer of ByteDance, Chinese-owned holding company TikTok. Mayer was seen as a frontrunner at Disney to get the top position but was passed over earlier this year to succeed Bob Iger in favour of Robert Chapek.  The pandemic has seriously weakened Disney as Covid-19 forced it to abandon its profitable parks and cruise ship companies. Iger took back some control of the business and remains the executive chairman while Disney scrambled in March to compile a $6 billion debt bid. It has laid off staff and cut wages with Chapek deciding to halve his pay and Iger promising to give up one completely  Before lockdown, TikTok was already a major hit  and has seen its success grow since. According to data from SensorTower which tracks downloads of devices, it was downloaded more than 315 million times in the first quarter.

Zhu had made efforts to do what Mayer is going to have to do now: convince America that TikTok is not a menace.
