Were you aware that the birth of hardcore pornography happened right here in San Francisco? Feel proud, kids. During the brief period of 1968 to 1972, the barriers fell for both strip clubs and porn theaters, and a boomlet occurred right in this very city in which theaters began flipping over into porn palaces one after another.

A new documentary short, Smut Capital of America, by local filmmakers Michael Stabile and Ben Leon explores this subject, and features interviews with John Waters, and a number of porn people from back in the day.
