October was a first litmus test for the good “New 52″ relaunch numbers, as it was the first month that allowed retailers to react to customer feedback on DC’s “New 52″ initiative in a meaningful way.

As a result, Marvel won a little less of the market share than usual got really spanked by DC in October, which took the Top 6 spots, along with a whopping 17 out of the Top 20 (and 32 out of the Top 50, and 60 out of the Top 100), as well as 50.97 percent of the unit market share and 42.47 percent of the dollar share.

DC’s average periodical numbers were down a bit from September and are now in the exact same area as right after the line-wide “One Year Later” event in May 2006, which had been DC’s high-water mark before the current relaunch. Back then, the average new DC comic book (not counting the now-defunct WildStorm) sold an estimated 50,519 units, the average new DC Universe comic book 59,505. In October 2011, now, it’s 51,280 and 59,146, respectively. These numbers don’t suggest we need to build a new ball park quite yet, but DC certainly did a great job of filling up the old one in a way that hasn’t happened since, well, 2006.

While a slight drop-off from September was to be expected, it turns out to be very slight indeed, because 16 of the “New 52″ titles didn’t drop at all, but rather increased in sales. They’re led by Animal Man, which, on the back of good reviews, saw an impressive second-issue increase of 16 percent. And even most of the rest of the bunch displays much slighter drops than we’re used to, for that matter. Only 16 of the percentage drops are in the double digits, and only four of those — Action Comics, Men of War, Superman and Blackhawks — are in the area you’d usually suspect. As a result, the average second-issue drop for the “New 52″ is a tiny 5.2 percent — a dream figure by any standard.

(Also, it’s worth noting that many of the books with the bigger second-issue drops came out in the last week of October. Technically, this means that they were disadvantaged, because all subsequent re-orders slipped into November. On the other hand, the first issues of those titles shipped in the last week of September, too, of course, so it should have evened out. In any case, we’ll get a clearer picture of what’s going on with the November chart.)
