Digital TV, the standard that recently went into effect, was developed for stationary televisions. TV stations nationwide, however, are beginning to broadcast signals for a new class of devices
that can show programming pretty much anywhere you can imagine. If enough people watch using the mobile TV technology, known as "ATSC Mobile DTV Standard," local stations will be able to charge more
for commercials and increase their revenue, according to The New York Times.
The technology will be used on new portable televisions with up to 10-inch screens, while smartphones and
laptops with special adapters will also receive the signals. Still, the devices have to be within about 60 miles of a broadcast tower for a clear picture.
