Since its launch, TikTok has become one of the world’s most popular social media platforms, using recommendation algorithms to connect content creators with new audiences.In April 2020, TikTok surpassed two billion mobile downloads worldwide. Cloudflare ranked TikTok the most popular website of 2021, surpassing Google. The popularity of TikTok has allowed viral trends in food and music to take off and increase the platform’s cultural impact worldwide.
TikTok has come under scrutiny due to data privacy violations, mental health concerns, misinformation, offensive content, and its role during the Israel–Hamas war. Countries have fined, banned, or attempted to restrict TikTok to protect children or out of national security concerns over possible user data collection by the Chinese government through ByteDance.
