WCOJ was perhaps best known for much of the time it has been in operation for the morning program hosted for over 40 years by station personality Art Douglas. By his retirement in 1995, Douglas had become a widely recognized figure in Chester County. In 1955, he came to Chester County and worked for WCOJ Radio in Coatesville. He was the "Voice of Chester County" for over 40 years. He became general manager but continued to do the morning show along with his sidekick, Jolly Joe Piscoglio, and Clifford E. DeBaptiste. He also, held the Phone Forum show in the afternoon. He retired in 1996 due to failing health.
