Dengeki Daioh

is a Japanese shōnen manga magazine published by ASCII Media Works (formerly MediaWorks) under the Dengeki brand. Many manga serialized in Dengeki Daioh were later published in tankōbon volumes under ASCII Media Works' Dengeki Comics imprint. The magazine is sold every month on the 27th. A yonkoma (4-panel) section of Dengeki Daioh called features various omake (bonus?) strips of the manga series published in it. The format is typically a normal drawing on the right side featuring one or sometimes more characters, and a vertical four panel strip on the left featuring characters from the associated series in super deformed form. Two special editions of the magazine called Dengeki Moeoh and Dengeki Daioh Genesis are sold bimonthly and quarterly, respectively.

History
The publication originated from Bandai's Cyber Comix magazine, which later became the short-lived Media Comix Dyne — it lasted three issues. After the publication of Media Comix Dyne was canceled, MediaWorks launched Dengeki Daioh as a quarterly publication in 1994. It eventually developed into a bimonthly magazine starting with the February 1997 issue released on December 18, 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 20th year of publication in 2014. 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.
