Jack Shafer in Slate:
The premature triumphalism of some bloggers indicates that they haven’t paid attention to how Webified journalists have become. They also ignore media history. New media technologies almost never replace old media technologies, they merely force old technologies to adapt and find new ways to connect with their audiences. Radio killed the “special edition,” but newspapers survived. When television dethroned radio as the hearthside infobox and cratered the Hollywood box office, radio became a mobile medium, and Hollywood devoted itself to spectaculars that the tiny TV set couldn’t adequately display. The competitive spiral has continued, with cable TV, VCRs and DVDs, satellite TV and radio broadcasters, and now Internet broadcasters entering the fray. The only extinct mass medium that I can think of is the movie house newsreel.
