"Shock Theater" refers to a television programming trend that emerged in the 1950s and 1960s, featuring classic horror films and low-budget B-movies. These shows often included a host who would introduce the films, providing commentary and engaging with the audience. The format became popular for its campy style and ability to entertain viewers with thrilling and spooky content. The term is closely associated with the late-night horror movie shows, such as those hosted by Zacherley and Elvira. These programs contributed to the cult following of horror films and helped to revive interest in the genre, influencing future horror-themed media and events.
