12/22/48 "EXPERIMENTAL BROADCAST # 1" The Show: Listed among Jack Benny's personal papers as "Experimental Broadcast #1" , this was a non-broadcast episode, seemingly done as an in house "try-out" for CBS. Why exactly CBS would need a "try-out" version of a show that had been on for 15+ years is something that I'm still trying to determine. This is a basically reworked version of the December 24, 1944 "tree-trimming" episode
