In the late 1980s and early 1990s, theme parks entered the business seriously. Six Flags Fright Fest began in 1986 and Universal Studios Florida began Halloween Horror Nights in 1991. Knott's Scary Farm experienced a surge in attendance in the 1990s as a result of America's obsession with Halloween as a cultural event. Theme parks have played a major role in globalizing the holiday. Universal Studios Singapore and Universal Studios Japan both participate, while Disney now mounts Mickey's Not-So-Scary Halloween Party events at its parks in Paris, Hong Kong and Tokyo, as well as in the United States. The theme park haunts are by far the largest, both in scale and attendance.
