MediaWorks launched Dengeki Daioh as a quarterly publication in 1994. It eventually developed into a bimonthly magazine in 1996, and later into a monthly publication when its name was changed to its current title, Monthly Comic Dengeki Daioh. In recent years, the magazine has taken to publishing information on anime and video games as well where half the magazine contains such information. Dengeki Daioh celebrated its thirteenth year of publication in 2007. Starting with the August 2008 issue, sold on June 27, 2008, Dengeki Daioh increased the number of manga series serialized in each issue which expanded the page count from about 700 to 900 pages per issue.
