The first issue of Electrical Design News — the original name — was published May 1956 by Rogers Corporation of Englewood, Colorado. In January 1961, Cahners Publishing Company, Inc., of Boston, acquired Rogers Publishing Company. In February 1966, Cahners sold 40% of its company to International Publishing Company in London In 1970, the Reed Group merged with International Publishing Corporation and changed its name to Reed International Limited.
Cahners Publishing Company acquired Electronic Equipment Engineering, a monthly magazine, in March 1971 and discontinued it. In doing so, Cahners folded EEE's best features into EDN,[not in citation given] and renamed the magazine EDN/EEE. At the time, George Harold Rostky (1926–2003) had been editor-in-chief of EEE. Rostky joined EDN and eventually became editor-in-chief before leaving to join Electronic Engineering Times as editor-in-chief.
