The latest rumor, as evidenced by the IMDb, suggests that the sequel to Tron will be called Tron: Killer App, a name taken from the phrase used to describe a computer software application that defines a turning point or milestone in technological history.

Incidentally, in an interview included with the 2-disc, 20th Anniversary Tron DVD, animator and director Steven Lisberger states that the character's name and title of the movie was coined because of its elecTRONic nature. In fact, Lisberger had no experience with the BASIC programming language and had never heard of the tracer on command so often attributed to the title when the name was created for a character used by Lisberger's Boston-based animation company for radio station commercials years before the movie was developed.
