Marvel will shrinkwrap a code for free digital copies with its Marvel: Season One graphic novels, which begin shipping in February (see “Marvel Reveals Trade Dress for Season One”).  This is the first “free digital with print” product in the graphic novel format. Marvel has been expanding its program of bundling digital copies with print in its periodical line, adding the Ultimate line to Avenging Spider-Man last week (see “Ultimate Line Adds Digital Bundles”). 
Marvel SVP Digital Peter Phillips told io9 that Marvel is also planning on taking the cross-promotion in the other direction; it's working on a program that will distribute coupons for print copies with digital purchases.
