Format
The use of a weekly publication format is unusual in the North American comics industry, a model traditionally based upon monthly publication. 52 is the longest weekly comic book series published by a major North American publisher. The record was previously held by Action Comics Weekly. The story was originally conceived of as being a chronicle of what happened in the "missing year" between the end of Infinite Crisis and the beginning of One Year Later. It would especially focus on how the world dealt with the disappearance of the "big three" heroes in the DCU, Superman, Batman, and Wonder Woman. As the series went on it became more of a way to set the stage for upcoming storylines in the DC Universe.
