The New 52

The New 52 is a 2011 DC Comics event marking the relaunch of its entire line with the publication of 52 new comic series, all beginning at #1. In September, 2011, DC Comics consolidated and relaunched their comic lines, discontinuing some series, and introducing yet other series, resulting in 52 titles, each with a new #1. That consolidation included the reincorporation of both the Wildstorm Productions and certain Vertigo properties into the mainstream DC Universe. The event takes its name from the previous DC event titled 52, in which DC Comics re-established the concept of the Multiverse in 52 Vol 1 which details the creation of 52 realities in the wake of the events of Infinite Crisis.
