All Channels Were Replaced

The first interruptions lasted only a few seconds.A brief replacement of normal programming. Easy to dismiss. Easy to ignore.Then the reports began to match.This transmission documents a global event in which broadcast signals across AM, FM, television, and emergency alert systems are replaced by the same unidentified audio. At first, engineers classify the interruptions as technical faults.Then they begin to repeat.Stations attempt to override the signal. They fail. Backup systems fail. Even isolated and powered-down equipment does not restore independent control.As the replacements increase in duration, official advisories become unreliable. Emergency systems are compromised. Verified information becomes impossible to confirm through traditional channels.Behavior begins to change.Decisions are delayed. Instructions conflict. Some continue to monitor the signal. Others disconnect entirely.There is no confirmed source.Only the realization that the systems used to coordinate response are no longer under human control.The broadcast continues while transmission remains possible.
