Emergency Broadcast System

1971: The United States Emergency Broadcast System is accidentally activated in an erroneous national alert after the wrong tape is played during a test of the system, ordering television stations to cease regular programming and broadcast the alert of a national emergency. Numerous investigations were launched, and several changes were made to the EBS as a result.
