The Tron franchise began in 1982 with the Walt Disney Pictures film Tron. It was followed by various film tie-ins, a comic series and the 2010 sequel Tron: Legacy. More sequels are planned, and a television series premiered on Disney XD in June 2012.TRON also existed as the TRON command in the early versions of the computer programming language BASIC. TRON stood for TRace ON, which prompted the program to print or display line numbers for each command line of a program as it ran, in order to assist in the debugging of the program. In the TRON movie, TRON became a character who worked in programs to defeat evil elements trying to subvert the program.
