Random question but I've often heard people refer to computer graphics in movies and television as "CGI" instead of "CG." I've always wondered: is this just a weird conflation of terminology from an era when Common Gateway Interface was a thing, around the same time fancy computer graphics technology was starting to take off in the 90s? Or is there there an alternative, legitimate reason why one would refer to Computer Graph*I"cs as "CGI?"
