ByteDance is the company that started TikTok. They also made an app called Douyin for use in China. In 2018, TikTok merged with another app called Musical.ly. This helped the app grow very quickly. By 2021, TikTok had over one billion users.

Some countries have banned the app for security or privacy reasons. In the United States, the app had to change owners. This happened because of laws about national security. In 2026, a new group of investors took over the US business. This group includes companies like Oracle.

The app stays the same for users. However, the rules for showing videos will change over time. The new rules will favor topics from America. TikTok is still a major place for people to watch and share clips.

TikTok is a famous social media platform for short videos.

People use it to share clips ranging from three seconds to 60 minutes long. The app uses a recommendation algorithm to connect creators with new audiences. An algorithm is a set of rules that picks content for you. This helps trends in food, fashion, and music grow very fast. By 2021, Cloudflare ranked TikTok as the most popular website in the world. It even surpassed Google in popularity that year.

The way the app works relies on its clever technology. The recommendation algorithm watches what you watch to suggest more videos. This helps creators and influencers find people who like their work. In 2019, the app even let creators sell items through video links. TikTok also partnered with the NFL to create special fan activities. In 2020, the app reported having nearly 800 million monthly users. By September 2021, that number grew to reach 1 billion users.

TikTok began with an app called Douyin. ByteDance launched Douyin on September 20, 2016, in China.

It was originally called A.me before the name change. ByteDance wanted to expand to the rest of the world. They launched TikTok for the international market in September 2017. On November 9, 2017, ByteDance bought a startup called Musical.ly for nearly $1 billion. TikTok and Musical.ly merged on August 2, 2018. This merger helped the app become a global success.

Many important facts show how huge the app became. In April 2020, TikTok had over two billion mobile downloads. In 2021, the company earned $4 billion from advertising. Some famous people like Will Smith and Justin Bieber joined the app. The company also deals with many different countries and laws. For example, India and Afghanistan have banned the app. Many other nations limit its use on government devices. This is often due to concerns about security and privacy.

Ownership of the app has changed recently in the United States. Because of national security concerns, the U.S. passed a law regarding the app. This led to a major change in who owns the U.S. business. On January 22, 2026, a new group took over the U.S. operations. This group includes Oracle, Silver Lake, and MGX. Michael Dell also holds a stake in this new venture. The app stays the same for users, but the algorithm will change. It will eventually favor American topics for people in the U.S.

TikTok is a global social media platform focused on short-form online video.

Users submit videos that vary in length from three seconds up to 60 minutes. The platform is accessible through a mobile application or a website. It has become one of the most popular social media tools in the world. Its massive reach allows viral trends in music, fashion, and food to spread globally. In 2021, Cloudflare ranked TikTok as the most popular website, even surpassing Google.

The core mechanism of the platform is its recommendation algorithm. This algorithm is a set of rules that connects content creators and influencers with new audiences. It works by analyzing user behavior to suggest relevant videos. This process helps content go viral by matching it with interested viewers. In 2019, TikTok expanded its functionality by allowing creators to embed merchandise sale links. The platform also entered partnerships, such as a multi-year deal with the NFL in 2019. This partnership included an official NFL account to provide marketing opportunities like hashtag challenges.

TikTok operates through different versions depending on the region. In mainland China, Macau, and Hong Kong, the platform is known as Douyin. While the user interfaces are similar, the two platforms operate separately. Douyin includes unique features like in-video face searching and services for booking hotels. ByteDance, the parent company, created TikTok as an overseas version of Douyin to reach a global audience. The founder, Zhang Yiming, noted that China represented only one-fifth of global internet users. Expanding globally was seen as a necessity to compete with other international peers.

The history of TikTok involves significant corporate growth and mergers. ByteDance launched Douyin on September 20, 2016. On November 9, 2017, ByteDance spent nearly $1 billion to purchase Musical.ly. Musical.ly was a startup that allowed users to create lip-sync and comedy videos. TikTok and Musical.ly merged on August 2, 2018, consolidating all accounts into the TikTok app. This merger helped the app grow rapidly. By 2018, TikTok was the most downloaded app in the United States. It reached 1 billion global downloads by February 2019.

Financial success and user growth have been remarkable. In July 2020, TikTok reported nearly 800 million monthly active users. By September 2021, that number reached 1 billion users. The company earned $4 billion in advertising revenue in 2021. Projections suggested revenue would rise from $9.89 billion in 2022 to $14.15 billion in 2023. However, some reports indicated that the company loses billions of dollars annually. Advertising growth in the U.S. was noted at 11% in March 2023. Major companies like Pepsi, Amazon, and Apple are among the top spenders on the platform.

Despite its success, TikTok has faced significant scrutiny and legal challenges. The platform has been criticized regarding data privacy, mental health, and misinformation. Some countries, including India and Afghanistan, have implemented full or partial bans. Many other nations limit its use on government-issued devices due to security concerns. In the United States, the Committee on Foreign Investment in the United States (CFIUS) investigated the company. This led to a Supreme Court case regarding a law that could force a sale or ban.

This law was based on national security concerns regarding ties to China.

A major restructuring occurred in the United States to address these concerns. On January 22, 2026, a spin-off company called TikTok USDS Joint Venture LLC was formed. This entity handles TikTok and other ByteDance properties in the U.S. The ownership structure changed significantly through a deal involving a consortium of investors. Oracle, Silver Lake, and MGX each hold a 15% stake. ByteDance retains a 19.9% stake. The remaining 35.1% is shared between Michael Dell and Vastmere Strategic Investments. Under this arrangement, the app remains the same, but the algorithm will eventually favor American topics for U.S. users.
