Musical.ly
The lip-sync app that minted U.S. teen fame — then merged into TikTok and handed short-form culture its next engine.
Overview
Normalized short lip-sync fame, creator duets, and teen influencer pipelines in the West. Its 2018 merger into TikTok transferred that audience into the app that would dominate 2020s meme culture.
