DC's comic output is constantly growing and evolving, as imprints and new waves of storytelling have hit the iconic publisher. In recent years, one of the most-discussed corners of the DC Comics world has been the Black Label line, which has taken a more mature and non-canonical take on some of the brand's most iconic characters. While Black Label's roster of books is continuing to grow, quite a few titles have endured shipping delays -- something that will hopefully change in the near future. DC Publisher Dan DiDio recently held a Q&A in the company's retailer-only Facebook page (via Newsarama), where he spoke about how they see the performance of the Black Label books thus far. DiDio called the line "extraordinarily successful", but stressed an effort in making sure future books don't suffer delays.
