Rumors that Mr. Pemberton would be fired have swirled all month, even appearing online as a done deal, after Women's Wear Daily reported June 1 that insiders expected his imminent departure. But Mr. Pemberton held on while all involved tried to work out differences over what direction the magazine should take.
A spokeswoman confirmed Mr. Pemberton's resignation, but declined to elaborate.
Hartle Media and the McEvoy Group bought Spin in February for less than $5 million and immediately named Mr. Pemberton editor in chief. He had been founding editor of Dennis Publishing's rival music magazine, Blender. He lost that job in September 2004 when Dennis laid off 15 employees.
