This is what happens when floppies don't put up the sales numbers that they should.
That's DC's own fault. They don't sell well. The last time they were #1 was in 2011 with the New 52 with Justice League #1 which sold well over 200k, since then they've had their ass handed to them by both MARVEL & IDW. As the New 52 began to continue into 2012 the JL continued with decent numbers of well over 100k, but nothing else was ding huge sales. Then MARVEL stepped in with AvX and Marvel NOW which has proven to be a better remodeling job than the New 52. Within 2012 everything of theirs started selling 10 - 20k less at least.
The New 52 was good to start sales wise, as things like GL, Detective Comics and Action Comics were in the top 10 for 2011, but it could be argued these were collector's items as new #1's. Because later on, those titles never really appeared in the top 10 since.
DC's biggest seller is Batman (big surprise) who has done great numbers since the New 52, but of course New 52 barely changed Batman all that much. His comic has been a number 1 monthly seller 8 times since the New 52, and 5 of those times were last year.
Now DC has had a few other times like Justice League of America #1 (again, probably a collector's thing)Forever Evil #1 and Superman Unchained, which makes sense how do you pass up what is the one of the best current Batman writers - Snyder paired up with Jim Lee's art and Superman? Plus, all the main Convergence titles have been selling well over 100k per issue, not bad and no surprise they were able to pull back in the old readers. This is an event that people really care about and not a quick, effortless and down right unsuccessful grab like Zero Year or holographic cover single issues of Future's End, Zero Year and Forever Evil and what nots.
I think DC's most consistent selling series so far are Batman, Justice League and honestly Harley Quinn. Those Harley has never made it number one her numbers are consistent in about the 70-90k range. But I find it very sad when iconic characters like Superman & Wonder Woman don't sell for ****. I think part of DC's problem is a lack of faith in their own product. They know and we all know Batman & JL can sell. Hire any monkey and Batman will sell... for the most part. They don't even have to try, though I want them to since Batman is my favorite. I see no effort on their part to say hey Batwoman, she's a diverse character lets push her more and promote her, nope cause now she's canceled.
But Convergence is ending, they got good numbers hence why these ads now, they probably no their short term stimulus (much like the New 52 launch) is over and need some money from somewhere, since I hear no hype for Darkseid War (prove me wrong, please) and who knows maybe their new direction they're taking in June with the end of the New 52 brand will deliver decent numbers but that PLUS the ads, well hard to say now.
