If you live in the United States, it appears as though the changeover from analog to digital television (DTV) signals is finally going through. After a couple years of preparation and lots and lots of ads running on your local television stations, it’s all supposed to swap over Friday.

The transition is meant to free up broadcast spectrum for emergency organizations and commercial wireless services. It also brings with it clearer television signals and the possibility of multicasting, or broadcasting multiple signals on the same frequency. Some stations transitioned early and have already been taking advantage of multicasting. In fact, the U.S. government says that 42 percent of TV stations already have made the switch.

But despite the delay enforced by the government earlier this year, it looks like there are still millions of people who haven’t bought digital converters. Either they haven’t gotten the message, they can’t afford a converter or they just don’t care.
