REMINDER: 2 PM is the first NATIONAL test of the emergency broadcasting system

Today is the first ever test of the National Emergency Broadcasting system, which can only be triggered by the White House. It will go off at 2 PM EST, and will preempt all television and radio programming for about 1 minute. Some radios and TVs may turn on automatically in response to the signal, and some may fail to show the "This is only a test" infographic. But don't panic - it is only a test.
