For the better part of the 20th century, "popular media" was synonymous with three major networks, radio, and the Hollywood studio system. Entertainment was a top-down, centralized affair. However, the advent of Web 2.0 and the proliferation of high-speed internet gave rise to what we now call "Tube entertainment content."

In old Hollywood, a studio head greenlit a show. Today, the algorithm does. Platforms like YouTube use complex machine learning to analyze watch time, click-through rates (CTR), and audience retention. If a video keeps people on the platform, the algorithm promotes it. This has led to the rise of "clickable" thumbnails (red arrows, exaggerated faces) and titles that exploit curiosity gaps. The result? is more direct, more sensational, and more addictive than its broadcast predecessor.
