Don't you just love it when someone claims they are the first... when they aren't even close! There were phonograph recording machines and booths available from the 1930s up through WWII where you could record personal messages to be sent to friends and loved ones. I happened on one of these during my stay at the US Navy's Great Lakes Training center. As I somewhat hazily recall, it was available around 1962-3 at the USO in Waukegan, Illinois. For a small amount I was able to record about a three minute message which was sent home to my parents to be played on their phonograph.
