It’s common to see someone mindlessly watching TikTok videos when they have some downtime. You’ll find silly memes, carefully crafted science communication, and everything in between. Anyone with an account can post videos or engage with content on the app. The result is that a variety of communities have formed. As with many social media platforms, TikTok’s positive and negative impacts are widely debated.

Along with Instagram Reels and YouTube Shorts, TikTok occupies an area of short-form media that’s experiencing an explosion of attention. TikTok claims it hadover one billion global monthly active usersin 2022. That’s good for the sixth most popular social media website. How did TikTok achieve such popularity?

Many point to Vine as the pioneer of this space that TikTok dominates. Vine was a similarly structured social media platform that took the online world by storm from 2013 to 2016. When Vine shut down in 2016, it left a void. That’s when TikTok (originally named Douyin) was released in the Chinese market by the company ByteDance. The app quickly grew in popularity and received an international release for iOS and Android in 2017.

ByteDance acquired the Musical.ly app for nearly $1 billion in late 2017. It shuttered Musical.ly in 2018 and merged existing accounts and data into TikTok. Since then, TikTok has continued to grow and gain relevance in pop culture.

TikTok is not new to controversy

TikTok isn’t without criticism or controversy. Several countries have banned it for periods of time. Many critics are concerned about how it handles user data and interacts with international politics. Other criticisms focus on how the content style influences young and impressionable audiences. There are also concerns about difficulties regulating the spread of misinformation.

Many organizations and governments, including the US, have considered banning TikTok. India’sPrime Minister Narendra Modi banned TikTokin June 2020, and a handful of other countries have done so permanently or temporarily.TikTok was bannedon most federally-owned devices in the US in late 2022, and many states have adopted similar bans. While former President Donald Trump failed to enact a TikTok ban in 2020,legislators may ban TikTok’s parent company, ByteDance, from doing business in the US.
