TikTok Broadway: Musical Theatre Fandom in the Digital Age explores the phenomenon of musical theatre fandom as it materializes on TikTok. Given the critical mass of TikTok and the app’s cultural influence across nearly every industry, this book unpacks different TikTok subcultures such as its thriving musical theatre community. The book argues that TikTok democratizes musical theatre fan cultures and spaces, creating a new canon of musical theatre thanks to the way virality works on the app. TikTok has energized fan practices, leading to innovative digital fandom aesthetics and a democratized approach to fan community formation. In this democratized mode of creation, fans and audiences dictate trending content and, subsequently, canon formation. On TikTok, fans can make shows popular (Six, Heathers: The Musical), make them commercially successful (Beetlejuice), and develop new shows (Ratatouille: The TikTok Musical, Bridgerton: The Musical). The power lies in the fans, who have a far greater reach than on Tumblr, Facebook, Twitter, and Instagram. From Beetlejuice and Six to Wicked and Ratatouille: The TikTok Musical, this book tells the story of TikTok Broadway, the Great Digital Way that has transformed musical theatre fandom in the digital age. TikTok Broadway intervenes into our collective understanding of how social media reimagines musical theatre fan practices.
