On today, October 3

WERD Atlanta was the first radio station owned and operated by African-Americans, on October 3, 1949. (WDIA in Memphis was on the air in 1948 doing black—or Negro as it was called back then—programming, but the owners were white). Jesse B. Blayton Sr., a well-respected businessman and accountant from Atlanta purchased it in the late 1940s, and hired his son Jesse Jr. to run it. Also hired was "Jockey" Jack Gibson, among the most popular black DJs. The station was housed in the Masonic building on Auburn Avenue, then one of the wealthiest black neighborhoods in the United States. Located in that same building was the headquarters of the new Southern Christian Leadership Conference, led by Dr. Martin Luther King. It has been said that King would beat the roof of the office with a broomstick as a signal to send the microphone down when he wanted to make public addresses^{[citation needed]}.
WERD was at 860 AM. While WDIA had Nat D. Williams, WERD had "Jockey Jack" Gibson, a friend of Blayton from Chicago^[1]. Blayton sold the station in 1968^[2].
