Real World article
(written from a Production point of view)

Retroactive continuity, known as a retcon for short, is the alteration of previously established facts in a fictional work, either through the addition of new, conflicting information, or by changing the original work directly.

Star Trek has had large amounts of such material, especially when episodes of Star Trek: The Original Series and Star Trek: The Next Generation were remastered.

This article is a stub relating to real-world information such as a performer, author, novel, magazine, or other production material. You can help Memory Alpha by fixing it.
