At the time of Infinite Crisis, DC was close, or even a month or two in first place IIRC.
Now:
Marvel Comics had the largest percentage of the top 300 comics with 51.86% of the total units sold followed by DC Comics with 31.68%.
Top 20 books, 15 Marvel, 4 DC, 1 Dark Horse.
Dollars wise, Marvel made $13.3 million, to DC's $7.6 million with comics.
Even in trades, which used to be a DC strong suit, while DC sold slightly more trades 31.93% to Marvel's 30.06%, Marvel made more money off of them $2.2 million, to $1.8 million.

How did DC go from pretty close, to pretty far away?
