Food for thought:
The Flash has been consistently selling about 38-39,000 copies of each issue since May (with a spike for Villains Month). And that’s a typical mid-range book, successful enough that DC is putting the creative team on Detective Comics. Digital figures aren’t available, but articles typically estimate digital sales at about 15% of print sales across the board. So let’s say around 44K between print and digital.
“Arrow” reportedly pulled in 3.17 million viewers for “The Scientist” guest-starring Barry Allen.
A lot more people watch TV than read comics.
