"From the Good Old Days...To the Possible Present"
It's kind of funny that today's "good old days" are really what passed for the "present" they were referring to! Disneyland is so old that it's fun to see how its attractions have aged. For instance Main Street, USA was really based on streets that only was 40-50 years old at the time...now it's 50 years old itself! The "future" of outer space in Tomorrowland is so commonplace and everyday now, people really only go into space now to launch new TV satellites or something mundane. Then there's General Electric that sponsored the attraction. I'm sure GE wouldn't be so eager to sponsor an attraction today given that it owns NBC, which owns Universal, which owns Universal Studios.
My how times have changed. Fortunately the important parts of Disneyland never do.
