Nion McEvoy, scion of the family that once owned the Chronicle, along with a small San Francisco publisher, Hartle Media, are buying the monthly rock ‘n’ roll magazine Spin and firing publisher Jake Hill and editor Sia Michel. The New York Post, San Francisco Business Times and other media say McEvoy (son of former Chron publisher Nan Tucker McEvoy) and Hartle (publisher of the glossy 7×7 Magazine) will pay about $5 million, but when the assumption of liabilities is included, the actual price is in the mid six figures. The seller is Vibe/Spin Ventures LLC., owned by Miller Publishing chief executive Robert Miller, Quincy Jones, David Salzman and the private equity firm Freeman Spogli. They bought Spin from founder Bob Guccione Jr. for $42 million in 1997. According to the Post, Andy Pemberton, founding editor of rival music mag Blender, will be Spin Media’s new editor-in-chief, while Malcolm Campbell, who was Spin’s publisher until he left to launch Blender, will return as Spin’s publisher. The Business Times says Spin reportedly has been losing $3 million a year and its ad pages have been declining.
