In Broadcast Hysteria, A. Brad Schwartz examines the history behind the infamous radio play. Did it really spawn a wave of mass hysteria? Schwartz is the first to examine the hundreds of letters sent directly to Welles after the broadcast. He draws upon them, and hundreds more sent to the FCC, to recapture the roiling emotions of a bygone era, and his findings challenge conventional wisdom. Relatively few listeners believed an actual attack was under way. But even so, Schwartz shows that Welles's broadcast prompted a different kind of "mass panic" as Americans debated the bewitching power of the radio and the country's vulnerability in a time of crisis. Schwartz's original research, gifted storytelling, and thoughtful analysis make Broadcast Hysteria a groundbreaking work of media history.
