Here is a pocket history of contemporary mass control through drama
It started with scripted movies and TV shows. These were filmed theatrical productions using actors who were suited for close ups, not just for beholding across an auditorium. They didn't need to project their voices, for example. They could speak in low, intimate whispers or gravelly drawls. They could have, and ought to have, small and subtle flaws. Scars. Moles. Wrinkles. Crooked teeth.. These vocal, facial, and bodily eccentricities caused a sense of identification in audience members, who knew themselves to be imperfect too.
