Something I've noticed as an insomniac with cable tv frequently on late at night. The Emergency Broadcast System has changed. It still cuts off shows and makes those disturbing BEEP BEEP BEEP honking sounds, but it doesn't have the Hal voice telling us what's going on (like on weather radio where the Hal NOAA voice starts talking about storms or dangers.) It just displays text saying it's a required test, and hangs there. Eventually a scrolling thing comes on the screen saying "turn to channel X". Then channel X says it's a weekly test.
