History Main / NoThemeTune

* ''Series/{{Glee}}'', interestingly, has no theme song, despite being a musical show. Just the title in lowercase on a black background with the crescendo of the music from the previous scene over it. Once, it was Mr. Shuester's license plate, despite being done normally later in the episode.

In the case of TV series, this is due to increased commercial time reducing the amount of available storytelling time; therefore, an opening credits sequence lasting 2 minutes with a full-fledged theme playing every week takes away from valuable storytelling time. Examples include ''Series/{{Lost}}'', ''Series/{{Heroes}}'', ''Series/{{Supernatural}}'', ''Series/{{Invasion}}'', ''Series/{{Surface}}'', ''Series/{{Threshold}}'' and ''[[Series/TwoBrokeGirls 2 Broke Girls]]''. As for films, the recent trend - especially with sci-fi and fantasy films - has been to not have any credits or theme music, and sometimes not even an on-screen title, until the ''[[CloseOnTitle end]]'' of the picture. Some {{anime}} series have left out the OP in the first or last episode (or both).

* In modern anime (especially during the 2010s), it's often common for shows to not include the opening in the first episode and/or in the last episode of the series and/or of the season. Although sometimes, the opening plays in the end of the episode in place of the normal ending.

* Episode 1 of ''Popotan'', although we do see some flashy subtitles of various people who worked on it as it begins.

* There were some episodes in the broadcast of ''Anime/PuellaMagiMadokaMagica'' that closed with credits rolling over the screen and opened without the series opening. The DVD and UsefulNotes/BluRay releases did change this up by adding two new themes.
* An example similar to ''Madoka Magica'' happens with the ''Anime/LoveLive'' franchise. Whenever an episode is going to end with the idols doing a live, the closing credits play over the last scene rather than that season's ending theme showing up on that episode.
* Most episodes of the second season of ''Literature/ReZero'' skips over the opening (and sometimes the ending) entirely with only a few of them (episodes 2, 5, 8, 19, 21) actually having one.

* ''Series/{{Castle}}'' has a sort of introductory musical sting, but no real theme. The credits play over the first act.

* Most episodes of the second season of ''LightNovel/ReZero'' skips over the opening (and sometimes the ending) entirely with only a few of them (episodes 2, 5, 8, 19, 21) actually having one.

* In modern anime (especially during the 2010s), it's often common for shows to not include the opening in the first episode and/or in the last episode of the series and/or of the season. Although sometimes, in the first episode, the opening plays in the end.

* In modern anime (especially during the 2010s), it's often common for shows to not include the opening in the first episode and/or in the last episode of the series and/or of the season.

* ''WesternAnimation/SecretMountainFortAwesome'' don't have one either, just a title card accompanied by a yell.

* ''WesternAnimation/RegularShow'' opening begins with a single synth note, with the actual theme song being played during the end credits.

* ''Series/{{Jericho}}'' shows the show's name with the sound of a radio tuning amid static. With brief messages given in Morse code.

* ''WesternAnimation/TheSpooktacularNewAdventuresOfCasper'' just has the show's logo followed by the title of the first short.

* ''WesternAnimation/TheOwlHouse'' has its theme song skipped for the first episode.
