[2] Based in the fictional city of Metropolis, the paper employs Clark Kent, Lois Lane, Jimmy Olsen, and Perry White as its editor-in-chief.

In Superman #5 (Summer 1940), the publisher of the Daily Planet is shown to be Burt Mason, a man who is determined to print the truth even when corrupt politician Alex Evell threatens him.

[6] In the Silver and Bronze Age universes, Clark's first contact with the Daily Planet came when reporter (and future editor) Perry White came to Smallville to write a story about Superboy, and wound up getting an interview where the Boy of Steel first revealed his extraterrestrial origins.

[7] During Clark Kent's years in college, Perry White was promoted to editor-in-chief upon the retirement of the Daily Planet's previous editor, the Earth-One version of George Taylor.

Edge proceeded to integrate Metropolis television station WGBS-TV's studios into the Daily Planet building, and named Clark Kent as the anchor for the WGBS evening news.

[12] After the 1985–1986 miniseries Crisis on Infinite Earths, many of these elements, including Morgan Edge buying the Daily Planet, were retroactively changed or eliminated from the Superman canon.

[13] During this era, the Planet's major competitors in Metropolis include the tabloid newspaper the Daily Star, WGBS-TV (which also employed Jimmy Olsen and Cat Grant for a time), and Lex Luthor's various media operations.

The story established that while Lex Luthor, in the revised history, owns every media in Metropolis and uses it to enforce his public image as a wealthy benefactor, the Planet had always stood free, refusing him ownership and even condemning his actions in editorials signed by Perry White himself.

When he failed to do so, he forcibly shut down the Planet as part of an attempt to force Perry White and Lois to turn over any information they had on Superman that they haven't released to the public.

Eventually, Superman turned the public to his favor and Sam Lane was seen in a bad light after his soldier John Corben AKA Metallo ruthlessly endangered civilians.

These events lead to the people of Metropolis no longer looking at Lex Luthor as a savior and The Daily Planet becomes the city's top-selling paper, as well as a major player in media.

In Final Crisis #2, the villain Clayface triggers an explosion in The Daily Planet building, greatly damaging the offices, leaving many injured and at least one person dead.

Despite the chaos of Final Crisis and more than half of humanity being enslaved by evil, the newspaper continues to spread news and inform the public via a printing press in Superman's Fortress of Solitude.

[16] In Action Comics, it is revealed that in the new history/universe, Clark Kent begins his journalism career in Metropolis roughly six years before Galaxy Broadcasting merges with the Daily Planet.

Along with being a writer for The Daily Star, partly because editor George Taylor was a friend of his adopted parents, Clark is an active blogger who speaks against political corruption and reports on the troubles of everyday citizens who are not often the focus of news media.

But after rising tension between himself and Lois, as well as with Galaxy Broadcasting head Morgan Edge, Clark concludes that the Daily Planet is now more concerned with ratings and internet page views than actual journalism.

[17] In virtually every incarnation of the era inhabited by the Legion of Super-Heroes, the Daily Planet is depicted as a fixture in Metropolis, and one of Earth's major media sources.
