If we're going to get into the future of the medium, I think the comics industry needs -- to use an eyerolling corporate buzz phrase -- a "paradigm shift."
I agree that the monthly floppy is not sustainable and not going to attract new readers and that the key to the future success of the industry is digital. I think going forward, kids will be consumers of physical media less and less to the point where there might not be any need for physical media at all. This will be true for books, music, magazines, newspapers, and yes comics. Right now, we're in the in-between/migration phase where we're moving to digital, but are still trying to sustain the physical. So, right now, things are a bit chaotic for the different media whose content was traditionally delivered exclusively in physical form.
However, why I said there had to be a paradigm shift is because there has to be a complete ground-up re-thinking of how comics are created, distributed, and purchased. Yes, we can make digital copies of comics, but if they're just going to basically be scans of the printed page that you have to buy per issue, then that won't attract a lot of people.
I would propose:
FORMAT: Comics should be rethought and redesigned to take advantage of everything digital has to offer. Quite frankly, digital comics shouldn't be something you read a panel at a time on a cellphone the way a lot of "digital first" comics seem to be done today. If I were to care about digital comics, you would have to create something that I can download and experience on my widescreen television because even on a tablet, a comic page often looks too small and so you have to zoom in thereby losing the effect of taking in the entire page at a glance, inventive panel-to-panel progression, and allowing for double page spreads. Just think of a Jim Lee double pager, say the one from his Justice League #1 where Batman is being fired upon and being able to view that on your big screen TV from your easy chair.
Other digital tricks can be added to the comics to enhance the experience (like behind the scenes interviews with the creators, being able to switch from original art to fully rendered page, clicking an icon to get Who's Who info on each character in the story, etc.), but the point is that comics need to be TV-compatible because a person's TV is the hub of their home entertainment experience. If comics are to survive, they should morph themselves into another onscreen entertainment option, allowing the viewer to switch seamlessly from TV to Blu-Ray to Internet browsing to streaming to reading a digital comic.
Give me this to fill my widescreen TV, and I'll care about digital comics and never buy another print comic again:
PRICING: I don't think digital comics will be a viable option to most comics fans on a per-comic basis at the same price that a paper comic costs. If printing costs are being saved, that savings should be passed along to consumers. I get that right now, the companies don't want to do this because the retailers would have a shitfit, but I'm afraid that over time, the comics companies are going to have to face facts that print is dying. It's dying everywhere, and comics will be no exception. I think what would encourage more fans to buy more comics is to have multiple pricing options. Say you want a single digital comic. That might cost 2 dollars. However, if you are willing to do a digital subscription, you can save money just like in the old days of print subscriptions. There should even be an option to do an all-in subscription where you get everything the publisher puts out for something like $30 a week. For those who can do it, it would be a good way to get readers to sample comics that they aren't currently buying. Another way is to offer a one-time half-price trial for a digital comic.
I hate to say this, but the direct market model is so limiting to getting and sustaining customers. Most people will never walk into a comic store, and as the years pass, kids will want all of their entertainment options to be digital. I don't think any kid under the age of 15 has ever bought a CD, and there's no reason to think that there's any long term solution that will permanently reverse this. Eventually, the comics companies are going to have to face the fact that the direct market is more of a hindrance than a help in expanding comics' reach.
CONTENT: I also think that comics should expand beyond the superhero genre to attract all those who have dismissed comics as a valid medium (like Bill Maher). Of course, DC has done good work with their Vertigo line, but what about comics that appeal to married women, career singles, etc. Japan has a wide variety of manga and something for every demographic (even though we only get the young male demographic stuff over here). We should do the same. There are TV shows and movies that are geared toward women, why not comics? A 45 year old woman might not walk into a comics store, but she might be tempted to download a digital comic that appeals to her demographic. Whatever prose novels such a woman might read could be done in the digital comics format.
In order for the comics industry to survive and thrive beyond going from one short term gimmick to another as it as since the industry's inception in the 1930s, it has to rethink itself and take itself seriously as a viable entertainment option that has wide appeal, content for any and every demographic, a convenient method of acquisition, and attractive pricing. Digital comics that take advantage of the widescreen television real estate to create eyepopping images and stories will make comics a more ubiquitous presence in the household.
