BookTok is a clear example of a subculture that exists mainly online. It is a community centred on TikTok where readers and creators share book recommendations, reactions, reviews, humour and reading-related trends.
System: BookTok operates through TikTok, a digital media platform whose recommendation algorithms distribute short videos according to signals such as viewing time and interaction. This allows participants with similar interests to find one another without sharing the same physical location.
Example specifics: BookTok became especially prominent from 2020 onwards. Members use recognizable hashtags, expressions, video formats and categories, such as “BookTok made me buy it,” to communicate shared interests. Although it influences physical bookstores and publishing, its community interaction, cultural production and visibility remain primarily online.
Impacts and implications: BookTok has helped some authors and older books gain renewed attention, while readers can discover works and discuss them with a global community. Authors, publishers, booksellers and readers may all benefit from increased visibility and sales. However, recommendation algorithms may repeatedly promote already popular books, narrowing the range of works users encounter. Commercial sponsorship can also make it difficult to distinguish personal recommendations from advertising.
This example connects to identity because members express who they are through reading preferences and community participation. It also demonstrates expression, since participants represent ideas and emotional responses through videos, reviews and shared language. From a systems perspective, users, creators, publishers and TikTok’s algorithms interact to shape which books become visible.
A common misconception is that a subculture must be completely separate from offline life. A subculture can exist mainly online while still producing offline impacts, such as bookstore displays or book-club meetings.
Exam technique: This is shared SL and HL content within the cultural context, specifically subcultures (4.1D). In an IB response, do not merely name BookTok. Explain the digital system, its community practices, and its different impacts and implications for at least two groups.
