Television did not kill radio, neither did the Walkman, nor will the Internet.
During the past 10 years technology has dramatically broadened radio (and other audio) programming. It began in the mid-1990s with “streaming” audio over the Internet. By the end of the decade XM Satellite Radio and Sirius Satellite Radio were launched. Since then, digital radio has continued to expand with the addition of podcasting, offering time-shifted radio programming, and HD Digital Radio, offering superior sound quality and additional AM and FM frequencies.
