Paul O'Brien writes at The Beat:

Dark Reign continued in March, with more tie-in issues and miniseries. As with the Initiative books a couple of years ago, Dark Reign isn’t a crossover so much as an umbrella branding for books that use the backdrop of Norman Osborn running the show. How much difference is it making to sales? Well, look below.

March also saw the start of the WAR OF KINGS crossover among the various cosmic superhero books, and the “Messiah War” crossover between X-FORCE and CABLE. And, after more than three years, ULTIMATE WOLVERINE VS HULK #3 finally emerged blinking into the daylight.

You won’t be surprised to learn that Marvel had the largest share of the North American direct market once again, beating DC by 47% to 28% in units and 43% to 27% in dollars.
