Goodman, now disconnected from Marvel, set up a new company called Seaboard Periodicals in 1974, reviving Marvel's old Atlas name for a new Atlas Comics line, but this lasted only a year and a half. In the mid-1970s a decline of the newsstand distribution network affected Marvel. Cult hits such as Howard the Duck fell victim to the distribution problems, with some titles reporting low sales when in fact the first specialty comic book stores resold them at a later date.[citation needed] But by the end of the decade, Marvel's fortunes were reviving, thanks to the rise of direct market distribution—selling through those same comics-specialty stores instead of newsstands.

What new venture did Marvel's founder begin after leaving the company in the 1970s?
