This is a good idea – iFanboy have spoken to many comic retailers accross the US after their opinions on the increasing amount of digital comics and their effects. I may get onto some around the UK and see what they have to say!
Most of the debate about digital comics and the future of paper comics centers on the readers’ preference in media. They either do or don’t mind the digital form over paper. The next hot topic is the issue of price, and as we’ve seen on this site many times before, opnions are varied, but it turns out that people want to pay as little money as they can. The acceptable amount depends on the individual consumer. Every once in a while, however, the issue of comic shops is brought up, the idea being that a full on successful onslaught of digital comics could spell doom for many comic book retailers.
I’ve got my own thoughts about the subject, but I’ve never worked in comics retail, so I went to some retailers to get their thoughts, since they’re the people it will affect the most, certainly more than most comic book readers.
