TikTok was launched in 2016 by a Chinese company called ByteDance. Originally, it was released in China under the name Douyin, but the company created a separate version called TikTok for international users. In 2017, ByteDance bought another popular lip-syncing app called Musical.ly, which was already popular in the U.S. and other countries. In 2018, TikTok and Musical.ly merged into one platform, bringing millions of new users to TikTok and making it a global sensation.

Since its rise in popularity, TikTok has continued to grow and evolve. It has introduced new features like longer videos, live streaming, and an advanced algorithm that helps users discover content they enjoy. The app has also faced challenges, including concerns over data privacy and bans in some countries. Despite this, TikTok remains one of the most influential social media platforms, shaping internet culture, music, and entertainment worldwide.
