Analog Nightlight

Analog television broadcasts that air (temporarily) after a switchover to digital television (DTV).

In January 2009, the American Federal Communications Commissionimplemented the Short-term Analog Flash and Emergency Readiness Act, so that analog TV viewers can receive an analog nightlight service for 30 days:

This action is designed to aid consumers who are not able to receive digital signals after the DTV transition on February 17, 2009, to provide them with access to emergency information … [and] to help consumers understand the steps they need to take in order to restore their television service.
