In the 1970s, the small company was one of the pioneers of the easy listening on the FM broadcasting radio spectrum with 2 stations in Manassas and Richmond.
Kellar acquired control of an FM station nearby, and went on the air with WEZR, licensed to Manassas, Virginia.
In 1970, the company took the successful easy listening format to the Richmond market when it acquired European classical music station WFMV (FM), which had been Virginia's first station to broadcast in multiplex stereo, and changed the call sign to WEZS.
In the early 80's EZ made a successful transition from easy listening to creating Contemporary Hit Radio stations in New Orleans (WEZB became B-97) and Pittsburgh (B-94).
At the time, EZ Communications operated 20 stations in cities such as Seattle, Washington and St. Louis, Missouri.
