I’m curious about the relationship of the TV show Futurama and the original Norman Bel Geddes exhibit from which it took its name. Are there any specific jokes or Easter eggs in the show relating to Bel Geddes and his life/philosophy? Or is there anything in any episode scripts that overtly references the original 1939 Futurama? The setting aesthetic is similar to the original, but I am more curious about jokes that are actually voiced or acted out.
This is as overtly a reference as you’re going to get:
The title card for the episode “The Inhuman Torch”.
The most noticeable one is right there in the first episode, immediately after Fry awakens in the year 3000. The cryogenic technician steps into the room and dramatically exclaims "Welcome to the World of Tomorrow!":
This seems to have been taken almost verbatim from the theme of the 1939 World's Fair, described by Wikipedia as "The World of Tomorrow", and evident in promotional material for the fair:
Also in one episode there was a "Past-o-Rama" exhibit- a sort of 'old world's fair' depicting a very inaccurate picture of old-New-York and twentieth century life (they thought Albert Einstein and Hammurabi were around during the days of Disco), this was probably meant as a parody of the 1939 futurama exhibit.
