What does EPCOT stand for?

The answer is: Experimental Prototype Community of Tomorrow. While today there'd be riots if certain things ever changed at EPCOT, Walt's original idea was around building a contained city where the problems of urban living could be tested and solved and were always changing.The original concept was too difficult to bring into reality, but by the early '80s the idea for a new park that showcased both the ideas of tomorrow and how people around the world live today was brought to fruition — and named in honor of Walt's vision.Source
