Several publications from Dengeki Bunko were later adapted into anime series, including Kino's Journey, Shakugan no Shana, A Certain Magical Index and Sword Art Online among others. After MediaWorks' light novel magazine Dengeki hp was discontinued, it was succeeded by a new magazine entitled Dengeki Bunko Magazine. In April 2013, the imprint celebrated their 20th anniversary with an exhibition.
