TikTok is a short-form video-sharing platform launched in 2016 by the Chinese company ByteDance. Originally introduced as “Douyin” in China, its international version was branded as TikTok in 2017. In 2018, it merged with another popular app, Musical.ly, which helped it gain rapid popularity, especially among younger audiences worldwide. The app allows users to create and share videos ranging from 15 seconds to 10 minutes, featuring music, special effects, and filters. Its algorithm-driven “For You Page” (FYP) is one of its strongest features, recommending personalized content based on user interactions and viewing history. This has made TikTok highly addictive and engaging, helping many creators go viral overnight. TikTok covers a wide range of content, including comedy skits, dance challenges, tutorials, education, news, and marketing. It has also become a vital platform for brands, influencers, and businesses to promote products through short, engaging campaigns. In addition, TikTok introduced live streaming and e-commerce integration, allowing direct shopping from the app. With over 1.5 billion users globally, TikTok has influenced modern digital culture, shaping trends, music, and even politics. Despite facing bans and controversies in some countries over data privacy, it remains one of the most influential social media platforms today.
