[2] The show was produced for white audiences and required Cooper to participate in scriptwriting and acting that specifically stereotyped African American culture through minstrel-style performances as this was considered to be of public interest at the time.
"[7] Cooper created The All-Negro Hour with the black community in mind as American broadcast radio programming in the 1920s looked to entertain a predominantly white audience.
[9] Although much of the content was comedic, there were segments of religion that Cooper featured such as live broadcasts of Sunday black church services in the Chicago area.
[6] The format of The All-Negro Hour continued to change as other radio shows such as Amos 'n' Andy and Beulah began gaining popularity across the country.
[6] Similar to the comedic strips in Amos ‘n’ Andy, Cooper created The All-Negro Hour: Luke and Timber and two other serial comedies in which he wrote, produced, and played a part in.
[10] Eventually, all live music and skits were replaced by pre-recorded tracks and Cooper became one of the first broadcasters to talk in between them, leaning into that of American DJing by adding his personality and voice into the content.
