A new radio show called "Amos 'n' Andy" aired for the first time on WMAQ on March 19, 1928. The actors were no strangers to Chicago radio as their program originally aired on WGN as "Sam 'n' Henry". Their first appearance on Chicago radio is said to have been on WLS in the late 1920s. Charles Correll and Freeman Gosden broke with WGN over syndication rights. General Manager Judith Waller saw the potential of the radio show and granted these rights to the duo as part of their WMAQ contract. Because WGN owned the rights to the characters Sam and Henry. So Gosden and Correll made some revisions to their act and renamed the characters for their new program Amos and Andy. Since WMAQ was affiliated with CBS at the time, Waller tried to convince the network to make "Amos 'n' Andy" a network program, but there was no interest. NBC brought the program to its Blue Network in the fall of 1929, paying the duo a record $100,000 for the right to broadcast the program.
