Proudly We Hail was a public service show for the Army and Air Force that aimed to strengthen the defense machine during a time of national emergency. The show was initially designed to bolster worker morale during the buildup of tensions in the Far East and just prior to the Japanese attack on Pearl Harbor. The episodes featured recruitment ads, a short play with a big-name Hollywood actor, and an interview with the star at the end. Some notable actors that participated in the show include Clark Gable, Robert Mitchum, Glenn Ford, Alan Ladd, and William Holden.

The radio show was first aired in 1941 on CBS for four months and later returned to the airwaves from 1946 to 1957, airing on as many as 1,300 radio stations. Hollywood producer C.P. MacGregor assembled the stations into his independent network for the first broadcast of the syndicated show, and there were 136 shows in the first series. The Library of Congress has possession of the MacGregor Collection masters and recording ledgers from 1931-1970, and the series continued through to episode 464, which was released in August 1957.
