The "DC Explosion" and "DC Implosion" were two events in 1978 – the first an official marketing campaign, the second a sardonic reference to it – in which American comics company DC Comics expanded their roster of publications, then abruptly cut it back. The DC Explosion was part of an ongoing initiative at DC to regain market share by increasing the number of titles they published, while also increasing page counts and cover prices. The so-called "DC Implosion" was the result of the publisher experiencing losses that year due to a confluence of factors, and cancelling a large number of ongoing and planned series in response. The cancellations included long-running series such as Our Fighting Forces, Showcase, and House of Secrets; new series introduced as part of the expansion such as Firestorm and Steel: The Indestructible Man; and announced series such as The Vixen which would have been the company's first title starring an African American woman. Former flagship series Detective Comics was also considered for cancellation. Some of the material already produced for these cancelled series was used in other publications. Several of the completed stories were "published" in small quantities as two issues of Cancelled Comics Cavalcade, whose title was a reference to DC's Golden-Age Comic Cavalcade series.
