of older city areas in the mid to late 1960s, changing economics forced these theaters to either close or offer something that television could not. In the 1970s, many of these theaters became venues for exploitation films, such as adult pornography and sleaze, or slasher horror, and dubbed martial arts films from Hong Kong. Content Films shot for and screened at grindhouses characteristically contain large amounts of sex, violence, or bizarre subject matter. One featured genre were "roughies" or sexploitation films, a mix of sex, violence and sadism. Quality varied, but low budget production values and poor print quality were common. Critical opinions varied regarding typical grindhouse fare, but many films acquired cult following and critical praise. Decline By the mid 1980s, home video and cable movie channels threatened to render the grindhouse obsolete. By the end of the decade, these theaters had vanished from Los Angeles's Broadway and Hollywood Boulevard, New York City's Times Square and San Francisco's Market Street. Another example was the Jolar Theater in Nashville, Tennessee, on lower Broadway, which was active until it burned down on April 14, 1978. By the mid-1990s, these particular theaters had all but disappeared from the United States; very few exist today. Homage The Robert Rodriguez film Planet Terror and the Quentin Tarantino film Death Proof, which were released together as Grindhouse in 2007, were created as an homage to the cinematic genre. A movie with a mock-trailer in Grindhouse, Machete (also by Rodriguez), was subsequently made into its own feature-length film, with care to include the scene from the Grindhouse trailer (originally filmed as a trailer of a movie that did not/would never exist). The Canadian release of Grindhouse included one additional faux-trailer, Hobo With a Shotgun, that was also subsequently made into a feature-length film. Similar films such as Chillerama, Drive Angry and Sign Gene have appeared since. S. Craig Zahler's film Brawl in Cell Block 99 is a modern example of the genre, along with his 2018 noir film Dragged Across Concrete. Manhunt, Red Dead Revolver, The House of the Dead: Overkill, Wet, Shank, RAGE and Shadows of the Damned are several examples of video games that serve as homages to the grindhouse movies. The author Jacques Boyreau released the book Portable Grindhouse: The Lost Art of the VHS Box in 2009 about the history of the genre. The field is also the focus of the 2010
