ユニバーサル・スタジオ・ハリウッド
Universal Studios Hollywood had featured Halloween attractions in 1986 and 1992. Bearing little resemblance to the modern event, the 1986 effort was actually a tram tour, and was marred by the accidental death of a retail employee who, like many employees at the time, had volunteered to perform in the event. The 1992 event was a direct result of the success of "Fright Nights" at Universal Florida the year before, but was not successful. Halloween Horror Nights officially launched at Universal Studios Hollywood October 9, 1997, running through the 2000 season. From 2001 to 2005, Halloween Horror Nights went on hiatus at Universal Studios Hollywood, then returned in 2006. It has continued yearly since. Between 2007 and 2014, Universal Studios Hollywood made use of Universal's House of Horrors, its permanent haunted attraction, as a part of Halloween Horror Nights, by re-theming it for the event.
