In September, DC is trying to recapture some of the sales and marketing success it had with the launch of its New 52 initiative a year before with a slate of zero issues for all of its core, New 52 titles (which is a slightly different lineup than it was a year ago). A zero-issue month is far from a new phenomenon for DC. It had one in 1994, coinciding with its Zero Hour crossover event. Zero issues have become, perhaps unfortunately, a much more common gimmick in the world of mainstream comics, especially in the super-hero genre. Still, there are times when I see the use of the odd numbering shtick.
