Why Your Kid Loves Being on TikTok

This week, TikTok got banned in India. Apple removed it from the iOS App Store in the country. However, the video-sharing app remains hugely popular with a young audience worldwide. Bloomberg Businessweek looked at why.
TikTok decides what videos to show by tapping into data, starting with your location. Then, as you start watching, it analyzes the faces, voices, music, or objects in videos you watch the longest. Liking, sharing, or commenting improves TikTok’s algorithm further. Within a day, the app can get to know you so well it feels like it’s reading your mind. That’s why Jade, the Oklahoma teen, mostly sees videos of people dancing, while her mom regularly gets clips of dog tricks.
