''The Adventures of Superman'' was comprised of five different radio series which ran consecutively from 1940-1951, all produced by Robert J. Maxwell. Most of the episodes starred [[Series/BeatTheClock Clayton 'Bud']] [[Series/ToTellTheTruth Collyer]] as Franchise/{{Superman}}, Joan Alexander as ComicBook/LoisLane, Julian Noa as Perry White and Jackie Kelk as ComicBook/JimmyOlsen. Aired for the majority of its run on the Mutual Broadcasting System.

Bud Collyer and Joan Alexander reprised their respective roles of Superman and Lois for the WesternAnimation/SupermanTheatricalCartoons and ''WesternAnimation/TheNewAdventuresOfSuperman''.
!! This show provides examples of:

* AcCENTUponTheWrongSylLABle: The introductory narrator in the very early installments announced the show as "the transcription feature, Super... MAN", which seemed to somewhat bury the lede when it came to the character. Everybody else on the show pronounced it the standard way, and within a year the error had been fixed.
* CanonImmigrant: A number of characters, and ideas (plus the name of the newspaper where Clark and Lois worked, as well as their boss) were actually invented for this radio show, but later appeared in the comics, including:
** Jimmy Olsen.
** Kryptonite. ''Not'' created to give Collyer a vacation, despite the myth.
** Inspector Henderson, who followed in Jimmy's footsteps and became a CanonImmigrant as well.
** The names "Daily Planet" (for Clark and Lois' newspaper) and "Perry White" (for its editor).
* CatchPhrase
** [[UpUpAndAway "Up, up and away!"]]
** "This looks like a job... ''for Superman!''"
** "Great Caesar's ghost!"
* ClarkKenting: Bud Collyer shifted vocal registers to differentiate between Clark and Superman. Justified since, because it was a radio show, it was the only way for the listeners to tell them apart.
* CounterEarth: Krypton is said to be this.
* CowboysAndIndians: Legend has it that this trope was ingeniously invoked to discredit the UsefulNotes/KuKluxKlan. A journalist who'd infiltrated the KKK gave details of secret meetings, passwords, titles etc. to the show's writers to use in a Supes vs. the KKK storyline. Soon enough, there were kids running around neighborhoods all over America dressed in pillowcases, being beaten up by their friend with the Superman pyjamas. The truth of all this is uncertain but there ''was'' such a storyline on the show, which Stetson Kennedy claimed responsibility for in his book ''[[http://stetsonkennedy.com/klan.htm I Rode With The Ku Klux Klan]]''.
* CrossOver: {{Franchise/Batman}} and {{Comicbook/Robin}} appear in many episodes.[[note]]Ironically, despite the character's concurrent popularity, no spin-off was ever attempted apart from the failed one-shot pilot "Batman Mystery Club" in 1950.[[/note]]
* DaEditor: Perry White of the ''Daily Planet.'' Best known in the radio show for being impossible to intimidate; he would often berate criminals and villains who had him in their power without the slightest regard for his own safety.
* ExpandedUniverse
* ForgottenPhlebotinum: One story revolves around a device that can receive sound from any past event. It isn't destroyed at the end, and the inventor helps Superman in the next story by using it. After that, it is never mentioned again, even when it might have been useful.
* ForGreatJustice: As stated in the OpeningNarration.
* IntrepidReporter: Everyone who worked for the ''Daily Planet''.
* TheKlan: [[NoCelebritiesWereHarmed Thinly disguised]] as The Clan of the Fiery Cross.
* OpeningNarration: It varied over the years, but the most familiar version (since it was heavily borrowed from in subsequent adaptations) starts with the page quote and continues:
--> Yes, it's Superman! Strange visitor from the planet Krypton, who came to Earth with powers and abilities far beyond those of mortal men. Superman, who can leap tall buildings in a single bound, race a speeding bullet to its target, bend steel in his bare hands! And who, disguised as Clark Kent, mild-mannered reporter for a great metropolitan newspaper, fights a never-ending battle for truth and justice!
* PowerMakesYourVoiceDeep: Collyer's Superman voice was deeper than his voice for Clark.
* StrawHypocrite: In "The Clan of the Fiery Cross", the Grand Scorpion is shown, near the end of the serial, to be one of these. In his own words, "Don't tell me you actually believe that 'pure American' hogwash! Riggs, I thought you were smarter than that."
* TakeCareOfTheKids: In this version of Franchise/TheDCU[[note]]Or rather, the "NCU" ("National Comics Universe"); the company wouldn't (officially) be called "DC Comics" until the 1970s.[[/note]], Robin's father asked Bruce Wayne to take care of his son.
* TarAndFeathers: In "The Clan of the Fiery Cross", the Clan attempts to tar and feather a child.
* ThoseWackyNazis
* TheWatson: ComicBook/{{Jimmy|Olsen}} was created so Superman could have someone to discuss the plot with.
* WeatherControlMachine:
** One of these was made by Lois Lane's uncle. He decided that TheWorldIsNotReady after criminals use the device to create storms so they can loot.
** In a post-war story, criminals cause a drought using a slightly more plausible method of cloud-seeding. Neither Clark nor Lois seems to remember the earlier machine.
