All Television Broadcasting Switches from Analog to Digital Format

Television stations across the United States powered down their analog signals on Friday, hours ahead of the long-awaited midnight deadline for the country to switch to fully digital TV broadcasts.

The transition day was a tense one at some stations, as they ended analog broadcasts and awaited calls from viewers still confused by the changeover and others having reception problems. According to Nielsen, about 2.8 million homes are completely unprepared for the transition. An additional 9.5 million homes are only partly ready, meaning that they may have upgraded some of their TVs, but not all of them.
