Thanks to the launch of "The New 52" back in September, DC was able to take over market share from Marvel in terms of both the amount of dollars spend and the number of comics bought. This hadn't happened for a long time and both October and November saw the publishers maintain their new-found lead. However, thanks to a decision to release their comics in all five weeks of December, Marvel is once again back on top. Just.
As
Bleeding Cool report, they started closing the gap back in November and DC's decision to release almost no comics in the fifth week of December meant that they've no fallen behind once again. As the site reports,
"Marvel rose from 33.3% to 34.43% of dollars spent in December 2011, while DC fell from 34.69% to 33.74%. And for the number of comics bought, Marvel led again increasing from 37.94% to 39.05% against DC falling from 39.66% to 37.72%."
Will Marvel be able to maintain their lead this month? Only time will tell...
