JOHANNESBURG - We've all heard of TikTok. It's fun to watch when you're bored.
Now there's BookTok, a growing platform where you can discover and share book reviews.
BookTok is so popular -- with more than 84 billion views to date -- that it's having an incredible impact on book sales worldwide.
The annual Frankfurt fair, the world's biggest publishing event, has made TikTok a partner for the first time.
The BookTok phenomenon is driven by the fact that TikTok is a visual platform, allowing people to show how they feel about a particular book.
