Hollywood output since 2010 is majority derivative across all media

Evidence

A similar study by Adam Mastroianni, using only the top twenty films each year, showed a similar pattern: “Until the year 2000, about 25% of top-grossing movies were prequels, sequels, spinoffs, remakes, reboots, or cinematic universe expansions. Since 2010, it’s been over 50% every year. In recent years, it’s been close to 100%.” Mastroianni shows a similar pattern for television, music, books, and video games. — Andrew deWaard, Derivative Media, 498

Categorization

• XREF: Extends the reader’s existing work on financial structures shaping artistic form: 25%-to-nearly-100% derivative output directly evidences the oligopoly thesis the book builds toward.
• SEED: The <25% before 2000 / >50% since 2010 / ~100% recent years step-change is a clean chart-ready datapoint for an essay on when and how derivative culture became structural.
