Your graph doesn’t factor in overships and the fact that they are producing much more comics to give the appearance of growth and stability in the industry. If you compare sales of individual titles to a decade ago and average it then it isn’t even close and I’d also wager that they’d be far worse if every issue was made returnable and digital sales were made public. They should do that if they are so confident with the product they are producing. This current model isn’t a problem for the companies that are subsidiaries of larger companies but it is killing comic stores.
