BEFORE TODAY, the apps of IDW Publishing were behind a walled garden. But now, the digital media company comiXology has been invited deeper into Eden.

IDW Publishing and comiXology are announcing Wednesday that they are growing their digital partnership by offering “same-day digital” content and launching eight comiXology-powered apps. The apps are: IDW Comics, Doctor Who Comics, G.I. Joe Comics, Star Trek Comics, Templesmith Comics, 30 Days of Night Comics, Transformers: Comics and True Blood Comics.

“All apps are live as of today, with new and old purchases alike syncing across the entire Comics by comiXology platform — iOS, Android, Web and Kindle Fire,” says comiXology in announcing the news, noting that “all IDW digital comics are also available for online purchases and reading through the simultaneous launch of a new digital comics store at read.idwpublishing.com. “

“This will be the first time we’re taking over a publisher’s apps, to power the apps for them when they’re already established,” comiXology CEO David Steinberger tells Comic Riffs.

Touting its integrated “buy once, read anywhere” approach, Steinberger continues: “There will be every IDW comic available that you’ve already purchased. That’s the beauty of this, and with a comiXology log-in, suddenly you can read the IDW stuff you bought [elsewhere].”

The announcement also notes that IDW “has committed to a full same day as print release schedule, a first for the company.” All new digital comics will sell at cover price; no “parity pricing” as with the digital comics of some other top publishers.

“The most impressive thing,” Steinberger tells Comic Riffs, “is that we’ve converted thousands and thousands of customers to our platform all at once — we did 1,100 IDW comics, which is really unheard-of in the app market. ... One platform replaces other platforms in one step.”

”Tons of women read ‘True Blood’ comics,” comiXology says as it seeks a widening range of readers and materials. (comiXology / IDW/.)

At October’s New York Comic Con, the companies announced that IDW’s library would be made available on the Comics by comiXology platform. ComiXology has already partnered with DC and Marvel, Image and Archaia, Dynamite and BOOM! Studios, hosting more than 16,000 digital titles.

Today’s deal is the expansion of a courtship that was years in the making for comiXology, which was founded in 2007 and has rapidly become a dominant force in digital comics delivery.

“I’ve been talking to IDW since early 2009, so this is a thrill,” Steinberger says. “IDW is so great because it matches our mission of getting comics out to as many [types of] people as possible.

“The choice validates our approach to the market.”
