TikTok is the short-form video app that reshaped social media and popular culture. The international version of Douyin, it was launched by Chinese tech giant ByteDance in 2016 and merged with Musical.ly in 2018 to accelerate its US growth. By 2024, TikTok had surpassed 1.5 billion monthly active users globally, making it one of the most-used apps on the planet.
The app’s recommendation algorithm is widely considered the best in the industry. Its For You page serves an endless stream of personalized short videos, and the system is remarkably good at figuring out what users want to watch — sometimes within minutes of a new account being created. This algorithmic precision is both its greatest strength and a source of concern.
TikTok hasn’t just created a platform — it’s created an entire economy. The Creator Fund, brand partnerships, TikTok Shop (its e-commerce integration), and LIVE gifting provide multiple monetization paths for creators. Music careers are launched on TikTok regularly, and the app has become a major driver of consumer trends in fashion, food, books, and more.
The regulatory picture has been turbulent. The US government has attempted to force a sale or ban of TikTok over national security concerns related to ByteDance’s ties to the Chinese government. A law requiring ByteDance to divest TikTok’s US operations was signed in 2024, leading to ongoing legal battles. Several other countries have restricted or banned TikTok on government devices.
ByteDance is one of the world’s most valuable private companies, with a valuation exceeding $220 billion. Beyond TikTok, ByteDance operates Douyin (the Chinese version), Lark (enterprise collaboration), and a growing AI division. TikTok’s advertising revenue reportedly exceeded $20 billion in 2023.
