The First 30 US Theaters

Although there is some conflicting information on seemingly official documentation of exact starting dates, the US locations listed below make up the first 30 theaters to play The Rocky Horror Picture Show as a weekly, ongoing midnight-only movie. Some articles mention the figure 30 specifically as the number of theaters showing Rocky Horror by the end of 1977, other say "around 30" theaters. While researching the topic, not coincidentally (at the time of this writing) exactly 30 theaters were found with starting dates in 1977. The following year saw an explosion of additional theaters, with over 200 known locations by the end of 1978. 1977 was a milestone year for the film as it slowly went from failure to breaking even to modest profit according to Variety.
