At about 1:55 pm today continuing for several minutes, all channels on all my set-top boxes were displaying EAS on the front panel and the TV's were seeing an "Emergency Alert System" test message that said this was a required periodic test.I have seen this happen at one channel only at various times but never on all channels at the same time. How often are such tests performed? Is it a Federal Law or do all networks do that on their own or was done only by Verizon FiOS?
I was watching a news program and they were in the middle of a discussion about terror threats and then this "Emergency Alert System" appeared on all channels so I was momentarily concerned until I realized it was only a test.
