In 1957, the New England Radio Corporation sold WMEX to the Richmond brothers. Max Richmond, one of the brothers, changed the format of WMEX to a rock-and-roll-dominant pop-music format (one of the first in the nation) and hired popular disc jockey Arnie Ginsburg away from smaller station WBOS (now WUNR). The hit format lasted from 1957 until March 1975. Max Richmond was reportedly a challenge to work for, with his alleged micromanaging and abrasive personality, yet none can deny his uncanny ability to spot DJ talent, and to keep his station—despite a poor nighttime signal in many suburban locations—a major player and innovator for many years.
