Since short-form video app TikTok, formerly known as Music.ly, burst onto the scene in 2018, it has captivated young audiences with its endless challenges, memes and lip syncs. The app even helped launch rapper Lil Nas X, and propel his hit "Old Town Road" to a record-holding 17 weeks on top of the Billboard charts. To outsiders, the app has a reputation for "cringey" content and comedic music videos produced by and for teenagers. But for Taylor Lorenz, a tech and internet reporter for The Atlantic, TikTok's unusual approach to social media is game-changing. On this week's episode of The Digiday Podcast, Brian Morrissey welcomes Lorenz back into the studio for a deep dive on the app that everyone is talking about, but not many understand. Here they discuss what TikTok is, what sets it apart from other platforms, and why it still has some growing up to do.
