Epcot celebrated it grand opening in October of 1982, as the second major theme park in Walt Disney World. This 300 acre park was launched as E.P.C.O.T, which stood for Experimental Prototype Community of Tomorrow, based on a concept first imagined by Mr. Walt Disney. Before he died in 1966, Walt imagined a community that could be developed as a revolutionary way of bringing people together in a shared environment.
When it first opened, Epcot focused on the theme of a future world type setting with attractions like World of Motion, Universe of Energy and Wonders of Life. As the park developed throughout the years, it moved out of the Prototype Community ideals and changed to the Epcot we see today (Disney even officially changed the park name to Epcot, dropping the acronym).
Epcot can almost be seen as two separate theme parks, as it is easily divided between Future World and World Showcase.
Many people refer to Epcot as the most educational of all Disney Parks, with Disney creating a balance of learning and entertainment, which certainly helps attract its millions of visitors each year.
