A Timeline of TikTok’s Evolution, From Dances to BookTok to the Supreme Court

In its infancy, TikTok was often described as an app for teenagers’ dance videos. In 2025, it’s a juggernaut with 170 million users in the United States and, according to the Justice Department, a national security threat that must be eliminated.

The platform’s path from a whimsical dance app to the target of a federal ban has been dotted with recipes, niche drama, micro trends, new entries into the popular lexicon and overnight megastars — as well as legal troubles, Senate hearings and, finally, a widely watched Supreme Court case.

Here’s a timeline of the app’s meteoric rise, and a reminder of the videos that dominated your algorithm, whether you wanted them to or not.
