Digital broadcasting is the practice of using digital data rather than analogue waveforms to carry broadcasts over television channels or assigned radio frequency bands. It is becoming increasingly popular for television usage (especially satellite television) but is having a slower adoption rate for radio.
Digital links, thanks to the use of data compression, generally have more efficient bandwidth usage than analog links, which allows a content provider more room to provide services, or to provide a higher-quality signal than had been previously available.
It is estimated that the share of digital broadcasting increased from 7% of the total amount of broadcasted information in 2000, to 25% in 2007.

“We spend all day broadcasting on the radio and TV telling people back home what’s happening here. And we learn what’s happening here by spending all day monitoring the radio and TV broadcasts from back home.”
