The concept for Disney's Hollywood Studios (originally called Disney-MGM Studios) came from an idea to have a movie pavilion at Epcot. Once Imagineers realized that the range of possibilities were larger than just one attraction, the idea for a 3rd theme park was born!
On its debut in 1989 Disney-MGM Studios (today known as Disney's Hollywood Studios) was so crowded that officials had to close its parking lot at only 9:15 a.m. - just about an hour after opening!
In 2008, Disney's Hollywood Studios hosted about 9.61 million guests, ranking it the fourth-most visited amusement park in the United States, and seventh-most visited in the world. That was the first year the park was known as Disney's Hollywood Studios, as prior to 2008 it was called Disney-MGM Studios.
