In serial fiction, the term "reboot" signifies a new start to an established fictional universe, work, or series. A reboot discards continuity to re-create its characters, plotlines and backstory from the beginning. It has been described as a way to "rebrand" or "restart an entertainment universe that has already been established".
Another definition of a reboot is a remake which is part of an established film series or other media franchise. The term has been criticized for being a vague and "confusing" "buzzword", and a neologism for remake, a concept which has been losing popularity since 2010. William Proctor proposes that there is a distinction between reboots, remakes and retcons.
The term is thought to originate from the computing term reboot, meaning to restart a computer system. There is a change in meaning: the computing term refers to restarting the same program unaltered, while the term discussed here refers to revising a narrative from the beginning. The first known use of reboot applied to an entertainment franchise was in a 1994 Usenet posting.
Say you’ve had 187 issues of 'The Incredible Hulk' and you decide you’re going to introduce a new Issue 1. You pretend like those first 187 issues never happened, and you start the story from the beginning and the slate is wiped clean, and no one blinks. One of the reasons they do that is after 10 years of telling the same story, it gets stale and times change. So we did the cinematic equivalent of a reboot, and by doing that, setting it at the beginning, you're instantly distancing yourself from anything that's come before.
Reboots cut out non-essential elements associated with a pre-established franchise and start it anew, distilling it down to the core elements that made the source material popular. For audiences, reboots allow easier entry for newcomers unfamiliar with earlier titles in a series.
In comic books, a long-running title may have its continuity erased to start over from the beginning, enabling writers to redefine characters and open up new story opportunities, allowing the title to bring in new readers. Comic books sometimes use an in-universe explanation for a reboot, such as merging parallel worlds and timelines together, or destroying a fictional universe and recreating it from the beginning.
With reboots, filmmakers revamp and reinvigorate a film series to attract new fans and stimulate revenue. A reboot can renew interest in a series that has grown stale. Reboots act as a safe project for a studio, since a reboot with an established fanbase is less risky (in terms of expected profit) than an entirely original work, while at the same time allowing the studio to explore new demographics.

A television series can return to production after cancellation or a long hiatus. Whereas a reboot disregards the previous continuity of a work, the term has also been used as a "catch all" phrase to categorize sequel series or general remakes due to the rise of such productions in the late 2010s.
A related concept is retooling, which is used to substantially change the premise of a series while keeping some of the core characters. Retools are usually part of an effort to forestall cancellation of a still running production.
Reboots and remakes are common in the video game industry. Remakes in video games are used to refresh the storyline and elements of the game and to take advantage of technology and features not available at the time of earlier entries.
In a lot of ways, a remake and a reboot are similar concepts. They are both brand-new versions of previous movies. However, "reboot" is more commonly used for film franchises, while "remake" is more often used for stand-alone movies.
Newhart is that rare beast in the TV world: a show where all of the retooling paid off because the producers were keenly attuned to what was and wasn’t working on their show.
