December 11, 1941, is not nearly as memorable a date as the one that lives in infamy. But that Thursday after Pearl Harbor is still an important moment in American history, because it's the day that Germany declared war on the United States and the U.S. immediately reciprocated. And it was on that date that President Franklin Roosevelt told his press secretary, Stephen T. Early, that the government should take over one of the national broadcast networks.
Early informed James L. Fly, the chairman of the Federal Communications Commission (FCC) and director of the newly created Defense Communications Board (DCB), that Roosevelt had personally directed Fly to acquire a national broadcast network for the government. The DCB had been created for just such a national emergency: Its mandate was to coordinate all communications (both military and civilian) in case of war or another national emergency.
