Grindhouse
（重定向自Grind House）
A grindhouse is an American term for a theater that mainly shows exploitation films. According to historian David Church, this theater type was named after the "grind policy," a film-programming strategy dating back to the early 1920s, which offered continuous showings of films at cut-rate ticket prices that typically rose over the course of each day. This exhibition practice was markedly different from the era's more common exhibition practice of fewer shows per day and graduated pricing for different seating sections of large urban theaters.
