TikTok, a favorite social media platform of tweens and teens, is evolving from featuring short-form quirky clips to live video and content related to everything from sports and gaming to cooking, fashion and beauty, says Bryan Thoensen, head of content partnerships. The social platform expects to see expanded educational content, which would boost users' time on the app while helping creators monetize their efforts, and generating more ad dollars, he says. So expect your children may be spending more time on the app.
