New York--Revolution, a digital tech publication from U.K.-based Haymarket Group, has suspended publication of its North American edition with the June-July issue. The monthly has a circulation of 70,000. Stovin Hayer, editor in chief, said the company is now working on the details to relaunch the magazine sometime this fall, although he would not elaborate. Both the British and Asian versions of Revolution will continue publication, as will a U.S. Web site.
