Films like Behind the Green Door (1972) and The Devil in Miss Jones (1973) broke ground by introducing actual narrative arcs to adult films. Directors like Gerard Damiano proved that adult videos could have cinematography, sound design, and character growth. This era established the blueprint for "feature-length" mature content.
