In 1968, while selling 50 million[citation needed] comic books a year, company founder Goodman revised the constraining distribution arrangement with Independent News he had reached under duress during the Atlas years, allowing him now to release as many titles as demand warranted.[1] Late that year, he sold Marvel Comics and its parent company, Magazine Management, to the Perfect Film & Chemical Corporation (later known as Cadence Industries), though he remained as publisher.[2] In 1969, Goodman finally ended his distribution deal with Independent by signing with Curtis Circulation Company.[1]
