Entertainment inventions solve the problem of experience at scale—allowing millions to witness events they could never physically attend. While writing took 175,000 years to establish and printing 1,000 years to mature, audiovisual media (radio, television, film) penetrated society within decades. Radio's 1920s "Golden Age" reached 80% of American households by 1939; television displaced radio as the home entertainment centerpiece by the 1950s. These inventions exhibit strong network effects and winner-take-all dynamics: once a format achieves critical mass (VHS over Betamax, streaming over DVD), alternatives collapse. They demonstrate costly signaling through production values—expensive content signals quality. The biological parallel is display behavior: peacocks evolved elaborate tails; studios evolved blockbuster budgets. Each entertainment medium copies its predecessor's ideas before finding its own form—radio borrowed from newspapers, television from radio, streaming from television.
