In 1968, a young filmmaker named George A. Romero shocked audiences with "Night of the Living Dead", a new kind of intense and unforgiving independent horror film. This film was released just after the abandonment of the production code, but before the adoption of the MPAA rating system. As such, it was the first and last film of its kind to enjoy a completely unrestricted screening, in which young children were able to witness Romero's new brand of highly realistic gore. This film would help to set the climate of independent horror for decades to come, as films like "The Texas Chain Saw Massacre" (1974) and "Cannibal Holocaust" (1980) continued to push the envelope.
