Popular media is no longer a monolith. Where once a single movie could capture the world's attention for weeks, today's attention is fractured across thousands of niches. A teenager in Ohio might be consuming completely different "popular media" than their parents in the same living room—one immersed in Twitch streams and Discord communities, the other watching cable news or linear television. This fragmentation has made it harder to define what is "popular," leading to a culture of micro-communities rather than a mass culture.
