TikTok Goes Global and Reshapes Content
TikTok merged with Musical.ly and launched globally, introducing algorithmic short-form video that captured a generation and disrupted every media industry.
In August 2018, Chinese company ByteDance merged its short-video app TikTok with Musical.ly, creating a global platform that would redefine social media. TikTok's innovation was its algorithm: rather than showing content from people you follow, it served an endless, personalized feed from anyone — making virality democratic and unpredictable. A teenager in Iowa could reach 50 million viewers overnight. The format — short, vertical, music-driven videos — proved irresistible, especially to Gen Z. By 2023, TikTok had over 1 billion monthly users and had forced every competitor (Instagram Reels, YouTube Shorts) to copy its format. It also became a geopolitical flashpoint, with the U.S. government attempting to ban it over data security concerns related to Chinese ownership.
