Ongoing series

• 1. Introduction

  ›

  Since 1938, "Action Comics" has demonstrated what an ongoing series can achieve: a run with no predetermined end. An ongoing series is defined by that absence. It differs from a limited series, which commits to a fixed number of issues before the first one ships. It differs from a one-shot, which stands alone without continuation. An ongoing series, by contrast, runs until something stops it.

  "Detective Comics" accumulated 881 issues between 1937 and 2011, making it the longest continuously published comic book in the United States. Even that record did not prevent the title from going silent, then returning in 2016. What keeps a series running, and what determines whether its end is called a finish or a cancellation?

• 2. The Fixed Schedule

  ›

  Monthly and bimonthly publication have traditionally set the pace for ongoing comics. A fixed schedule is a promise to readers, but many factors can push an issue to arrive late. When deadlines slipped, publishers historically inserted fill-in issues, produced by a different creative team, to keep the schedule intact.

  Fill-in issues often hurt quality, and the practice fell out of favor over time. The more common approach became simply delaying publication. Each choice carries a trade-off. A fill-in might preserve the schedule but introduce inconsistency into the run. A delay keeps the creative team intact while testing reader patience.

• 3. Finished, Cancelled, On Hiatus

  ›

  Any ongoing series "might run for decades and hundreds of issues or be canceled after only a handful of issues." The word used to describe that ending carries meaning. Comics publishing uses three distinct terms for what happens when a series stops appearing on shelves.

  "Finished" applies when a series ends because the story has genuinely concluded. "Cancelled" covers involuntary stops: low sales, editorial decisions, publisher bankruptcy, or reasons that go publicly unexplained. When a series is cancelled, an ending might be written for its final issues. Or the series may simply disappear without warning and never return.

  "On hiatus" is the most ambiguous of the three. A series on hiatus has paused but could theoretically resume. Many series are placed on hiatus but do not return even after several years. For creator-owned titles in particular, a hiatus sometimes signals not the end but the start of negotiations with a new publisher.

• 4. Changing Hands

  ›

  "Usagi Yojimbo" has moved through four consecutive publishers. Each transition kept the series alive past circumstances that would have ended a publisher-owned title. For creator-owned series, copyright belongs to the creator rather than the publisher. That ownership gives the creator one specific option: approaching other publishers about continuing the title under their imprint.

  When a publisher-owned series is cancelled, the copyright stays with the publisher. A new creative team can be installed, but the original creator may have no further say. Creator ownership changes that equation. The creator becomes the constant, and the publisher becomes, in principle, replaceable. For a series that outlasts one publishing home and then another, that constancy can stretch across decades.

• 5. Plans That Changed

  ›

  "Lumberjanes" was originally planned as an eight-part limited series. Strong sales and critical acclaim changed that plan. What began as a finite story became an ongoing series. It accumulated issues until it concluded after 75 of them, with a one-shot finale in December 2020. The full run stretched across six years.

  "Mickey Mouse" traveled a different arc. A Disney comic, it first appeared in 1943 as part of the Four Color one-shot series. It earned its own numbering beginning with issue #28 in December 1952. From that point, the series moved through many iterations and publishers, finally closing with issue #330 in June 2017 from IDW Publishing.

  A comic planned for eight issues becoming a 75-issue run captures what the ongoing format allows. The endpoint stays negotiable. Even a series that appears to have closed can sometimes return under a new number, a new publisher, or both.

• 6. Starting Again

  ›

  "Superman" was relaunched at least in 1987 and again in 2011. "The Amazing Spider-Man" was relaunched in 1999. The series later returned to its original numbering, designating issue #59 of the relaunched run as issue #500. In each case, the title's name survived the restart.

  "Fantastic Four" was relaunched in 1996, then again in 1997, and again in 2012. "Avengers" was relaunched in 1996, 1997, 2010, and 2012. Together, these examples show how a single ongoing title can accumulate multiple distinct eras.

  "Fallen Angel" took a different path. After DC Comics cancelled it, IDW Publishing relaunched the title under their own imprint. "Slingers," "Justice League International," and "Dungeons and Dragons: Fell's Five" remain cancelled. But as "Fallen Angel" demonstrated, a cancelled title is not always the final word.
