Long gone are the years where you learn American history through 300-page textbooks. Teens are looking to their fave app to do that: TikTok.

Some would argue that TikTok is just a glorified version of Vine, nearly a decade later. But the 15-second format (versus 6 seconds with Vine), which can be compiled into 60-second multi-clips, have allowed people to go much further than funny faces or potatoes flying around rooms. And during a time when people are stuck at home and looking for some combination of entertainment, social interaction, and hope, TikTok has gotten even more attention.

Even prior to the coronavirus pandemic, TikTok was growing fast (see its rise visualized here). But you might be surprised by what other TikTok niche areas are emerging on the social media platform.
