"Television was about ready for immediate commercialization when Pearl Harbor forced the industry to mark time, but engineers agree that the war has hastened electronic developments to a point that could not have been expected for 15 years under normal circumstances."
"By December of 1941, nine television stations in five cities held licenses for commercial operation. They were NBC, CBS and the Allen B. DuMont Laboratories in New York; the Zenith Radio Corporation and Balaban & Katz in Chicago; the Don Lee System and the Paramount Television Production in Los Angeles; the Philco Radio Corporation in Philadelphia, and the General Electric station in Schenectady. At that time there were 900 radio-broadcasting stations, including 46 FM stations."
