TikTok's Chinese owner ByteDance has signed a deal with investors to run its business in the US.

But what does this mean for the over 170 million Americans (or so the social media platform claims) who use the app?

The key may lie in how TikTok's recommendation algorithm - the powerful system that curates the platform's For You Page to predict content you might watch - is managed when it changes hands.

Social media industry expert Matt Navarra told the BBC the question will not be whether TikTok survives, but "what version of TikTok survives".

Currently, TikTok's system depends on huge amounts of global data and feedback loops, which can change recommendations in an instant.
