Admission to the Fair part was always inexpensive. I'm not sure if it was the 1940 or 1964 NYC Fair, that they got rid of the 'Midway'. The Midway was where they had hosts of nude dancers (M & F), clubs, bars, games of chance, all manners and kinds of adult entertainment. The admission to the Midway was not inexpensive. This is where they made the money to fund the science exhibits, like steam engines, etc.; and to make a hefty profit. I'm not sure which of the NYC Fairs thought the Midway wasn't suited for a wholesome fair, and got rid of it. And thus, lost their profit making ability. Without a Midway, NYC lost reportedly over $1 billion on the 1964 Fair and upgrades to infrastructure. (That's $7,800,000,000.00 in today's money.) The following Expositions were enormous money pits, and that's why they shrunk in size, and importance. Expo '67 was the best attended, and cost the least; but still left Canada with a $210,000,000.00 tab. ( $1.4 billion today).
