In 2017, the Chinese company ByteDance announced the launch of the international version of TikTok, entering overseas markets. In less than five years, TikTok has amassed over 1 billion global users. In Taiwan, the user base of TikTok has also grown rapidly in recent years. While early adopters were primarily children and adolescents, it has gradually expanded to other age groups. Unlike previous concerns about TikTok mainly focusing on addictive usage, cybersecurity, and political issues, this study attempts to examine TikTok's popularity from the theoretical perspective of acceleration and new forms of alienation proposed by Hartmut Rosa. It explores how TikTok's popularity leads to a potential crisis of "alienation." The key issue lies in the media characteristics of TikTok and its algorithmic operation, resulting in specific patterns of content production and consumption.
