>>149326496>wtf based and jewyThe story goes that in 1971 Marvel and DC had a gentleman's agreement to raise the prices on their books to 25 cents along with a page increase to 52 pages. But after a month, Marvel cut back to 36 pages and dropped prices to 25 cents while DC, for various reasons, was stuck at the 25 cent price tag for a year. At the same time, Goodman started offering distributors a bigger cut of the sales prices so they were more keen to stock more Marvel books and that's when Marvel overtook DC.
Although this casts a lot of doubt on that version of the story.

Actually going by that, the ABC (an independent auditing board) numbers show that Marvel had passed DC by 1967. A lot of the numbers more widely reported are based on publisher statements and it could be a full year before they'd get the real final numbers so those statements would likely be made with inaccurate or outdated information. Marvel's sell through rate (i.e. what customers were buying, not just what was being ordered) was something like 70 or 80% vs. DC's 40%.
