Alas, this is not the digital comics store that some (I, for exaple) have been hoping would launch in response to Amazon buying Comixology. Instead this is a distribution deal that enables Diamond Comics to offer comics publishers a digital option alongside Diamonds floppy and graphic novel distribution system.
Under the agreement, comics publishers pay a one-time fee of $1 page for production. Publishers can upload the source PDF to a Trajectory website, where it will be converted into the format for each retail channel, enabling Trajectory to distribute it to their network of vendors.
This deal comes in the wake of Amazon buying Comixology and of Graphicly, a competing distributor, shutting down following its acquisition by Blurb. The landscape of the comics market (both digital and print) is changing and the Trajectory/Diamond partnership will offer publishers distribution options beyond Amazon's fiefdom.
