In China, Douyin, owned by ByteDance, is the equivalent of TikTok. As the U.S. considers forcing ByteDance to sell TikTok, Douyin's importance to the company's financial success is highlighted. Douyin, with over 700 million monthly users, generates the majority of ByteDance's revenue. It earns from advertising, online shopping, and live streaming commerce. Douyin's growth in e-commerce and the launch of its own shopping app demonstrate its potential. Unlike TikTok, Douyin is only available in China and is popular among older users. It is also a platform for Chinese authorities to disseminate information and propaganda. However, it adheres to Chinese censorship rules, removing sensitive content. The future of TikTok and ByteDance's decision will be influenced by Douyin's continued success.
