To understand contemporary popular media, one must trace it back to the golden age of broadcast television. For decades, traditional networks acted as cultural gatekeepers. Content was linear, scheduled, and highly centralized. Popular media was defined by a shared cultural experience; millions of people watched the exact same broadcast at the exact same time, creating a unified cultural conversation the next morning.

Music hits, fashion trends, and slang now originate on video platforms before being picked up by traditional news outlets or marketing agencies.
