I think it was Futurama that sent up the 20th Century Fox name, and labelled it as 30th Century Fox in a mock endcap.
Long established "things" or traditions are not uncommon in the film studios, MGM's current lion mascot dates from the 1950s for a start, and Columbia's statue isn't too much different from how it looked in the 1920s. Warners Brothers hasn't changed too much (apart from that strange one they used in the 1980s) since coming along either, since it's shield design has its roots in the 1920s.
Going off-topic I often enjoy it at the cinema when films get to have fun with the film studio logo titles. Happy Death Day had the Universal logo restart multiple times. Zombieland Double Tap had Columbia deal with a couple attacking zombies. I can't recall which relatively recent 20th Century Fox film saw its logo and surroundings decaying.
