On February 17, 2009 all full-power broadcast television stations in the United States will stop broadcasting on analog airwaves and begin broadcasting only in digital. Digital broadcasting will allow stations to offer improved picture and sound quality and additional channels.

What Is Digital Television? Digital Television (DTV) is an advanced broadcasting technology that will transform your television viewing experience. DTV enables broadcasters to offer television with better picture and sound quality. It can also offer multiple programming choices, called multicasting, and interactive capabilities. Converting to DTV also will free up parts of the scarce and valuable broadcast spectrum. Those portions of the spectrum can then be used for other important services, such as public and safety services (police and fire departments, emergency rescue), and advanced wireless services.
