I still remember the first time I really started noticing the power of TikTok. It was back in seventh grade, right in the middle of COVID. Everyone was stuck at home, and suddenly it felt like the entire world was dancing on their phones.
One afternoon, I was scrolling through my feed when I saw two girls who seemed to be everywhere, on my “For You” page, in brand commercials, and even on Dunkin’ Donuts cups. They looked like sisters, and sure enough, they were Charli and Dixie D’Amelio.
At first, I was just surprised. How could two teenagers who posted dance videos suddenly become ambassadors for a massive company like Dunkin’? I did some research and found out they were TikTok creators whose dances had gone viral, so viral that companies, brands, and even entire industries were reshaping their marketing strategies around this new kind of fame.
That was when I first started to understand that TikTok wasn’t just entertainment; it was a kind of cultural diffusion.
The same way languages, music, and art once spread through trade or migration, TikTok was spreading culture through 15-second videos. A single dance created in someone’s bedroom could reach millions across the world in hours. Moves inspired by African hip-hop, Latin reggaeton, or American pop blended together into new routines that anyone, anywhere, could learn.
Teenagers in the U.S. were learning choreography from creators in South Korea. Songs from small artists in Nigeria were suddenly topping global charts. Food, fashion, and slang jumped across borders overnight.
Cultural diffusion used to take centuries. Now, it takes seconds.
