Reference materials for Star Trek spell the visual aide used by character Geordi LaForge as the acronym VISOR, instead of the word visor. Was this also the case in the scripts for the television show? Or were there some scripts (particularly early ones) where the prop is spelled in lower-case?
What I wonder is whether the producers took ideas from third-party merchandise and retroactively applied them to the television show, instead of coming up with the ideas themselves. If the term appeared in lower-case early in the show's scripts, before it appeared in upper-case in third party merchandise, that becomes strong evidence that the producers ret-conned material from third-party sources.
Star Wars is notorious for this practice (Palpatine's name, Coruscant, kyber crystals, etc.). Did the producers of Star Trek also do this?
