caused when later issues each took more than a month to complete. One contemporaneous report noted that although DC solicited issue #12 for publication in April 1987, it became apparent "it [wouldn't] debut until July or August". After the series concluded, the individual issues were collected and sold in trade paperback form. Along with Frank Miller's 1986 Batman: The Dark Knight Returns miniseries, Watchmen was marketed as a "graphic novel", a term that allowed DC and other publishers to sell similar comic book collections in a way that associated them with novels and dissociated them from comics. As a result of the publicity given to the books like the Watchmen trade in 1987, bookstores and public libraries began to devote special shelves to them.

Not wanting to work under a work for hire arrangement, Moore and Gibbons had a reversion clause in their contract for Watchmen. Speaking at the 1985 San Diego Comic-Con, Moore said: "The way it works, if I understand it, is that DC owns it for the time they're publishing it, and then it reverts to Dave and me, so we can make all the money from the Slurpee cups." For Watchmen, Moore and Gibbons received eight percent of the series' earnings. Moore explained in 1986 that his understanding was that when "DC have not used the characters for a
