Martha Wilkerson (1908-99) was the first star built by the network. During WWII she inherited the program GI Jive. That was our response to Tokyo Rose and many similar shows being broadcast to our troops. GI Jive was focused on the current hits. Eventually there was an oldies show "Jill's All Time Jukebox", playing memories.
She continued with the network until at least 1949.
Martha Wilkinson was one of the first big stars of AFRS. During WWII there was a show called "GI Jive", one of the DJ shows. Pretty non-descript until Martha became GI Jill and the voice of home.
