The first mX was published in Melbourne on 6 February 2001, hoping to capitalise on the Metro format, popular in Europe. The paper contained lighter news and sports articles, often containing strange stories and facts from around the world. The newspaper's approach was a much greater focus on entertainment than news than broadsheet newspapers, or even other tabloids. Melbourne Express, published by rival Fairfax Media, was this paper's competitor. Initially it used the same format, although it was released in the mornings rather than the afternoon. It began publication the day before mX, but was soon overtaken due to mX's much broader use of colour, its greater availability, and its lighter tone. In addition, mX had no explanation at its launch, allowing readers to assume that it stood for "Melbourne Express" and that it was the paper known by that name. Melbourne Express ceased publication on 7 September 2001. The broad success of mX contributed to reduced sales of the afternoon edition of News Corporation stablemate the Herald Sun, its last edition being published on 21 December 2001.
Sydney and Brisbane editions
Following the success of mX in Melbourne, Sydney and Brisbane editions were launched. On 4 July 2005, mX launched a Sydney edition. Sydney City Council was considering a tender to lease Sydney footpaths to News Corporation for $362,000 annually, and charge other free daily newspaper a similar fee if they use the same location more than 40 times a year. Other newspapers, that are distributed by sellers on streets, are concerned about the possibility that they may be required to also pay such fees. The Brisbane edition of mX was launched on 5 March 2007, with an expected distribution of 40,000 copies per day.
Format and content
Being a commuter newspaper, mX was much thinner than other daily newspapers. Central themes of most articles included U.S. celebrity gossip, new product lines, controversial events, rumours, celebrity trivia, and readers' gripes, amongst other attention-grabbing stories. Large photographs often appeared without any related story, only a caption describing their contents; conversely, news stories were rarely accompanied by photographs. Small, large, and full page advertisements were also a major contributor to the paper's overall make-up. The newspaper launched an app in 2013.
Sections
News – Short items of "legitimate" news such as national and state politics, included the next day's weather forecast. Started on page 2.
Juice – Celebrity gossip. Located on pages 4 and 5.
Sport – Located on the final two or three pages.
Brainwave – The puzzles page, including a crossword, Sudoku and various other word games. Also included a horoscope under the heading of "Should I get out of bed tomorrow?"
Talk – Essentially Letters to the Editor, although most letters were very short, having been sent via SMS. It was divided into several sections:
*Vent Your Spleen – Devoted to readers' SMSed complaints, comments and thoughts.
*Overheard – Devoted to humorous or bizarre conversations overheard and sent in by readers.
*Here's Looking At You – In which readers wrote messages to people on public transport to whom they are attracted, in the hope that they will reply and arrange a date, or just to anonymously compliment them. Originally such messages appeared in the general "Vent Your Spleen" section, but the practice became so popular that it was separated into its own section. "Here's looking at all of you" was the page-filling title page when the paper announced on 29 May 2015 its closure to the readers.
*Lost in Love – Readers' responses to a request from another reader for relationship advice, and an invitation to send replies to the next day's question.
*My Platform – A vox pop in which three people on the street gave a short response to a question. This section has been dropped.
Flicks – That night's movie listings. A movie review used to feature in the middle of every flicks page but that was dropped in 2011 due to the space being needed for session time listings.
The Box – Reviews of television programs screening that night.
Program – That night's primetime television listing. Was combined with "The Box"

Staples
Some mX editions had been stapled, as they tended to remain contained and not blow around as much. This decision was also based on the capabilities of publishing equipment and whether binding systems were installed at the production facilities.
St Patrick's Day editions had the blue captions replaced with green, and Irish themed stories fill the "Did You Know" and "What The?" sections.
Easter editions did not change colour; however, the "Did You Know" and "What The?" sections related to modern Easter stories.
Closure
On 28 May 2015, News Corp announced that the newspaper was closing down. The final edition was printed on 12 June 2015, and the corresponding mobile app was also closed down.
