I am sure the industry isn't doing as well as years before - not surprising in this economy. It would be interesting to know for sure how the numbers differ.
When the New 52 started, I saw an interview with Dan DiDio where he said titles rarely top 100,000 copies these days.
By way of comparison, this
is last year's list of the bestselling comics in Japan, where the comics industry is still thriving. (These are equivalent to trade paperbacks, so it's not a direct comparison, but the magazines where the series are first serialized usually have circulation in the millions.)
