Driven by changes in technology, 24 hours TV news has exploded in our faces. This explosion has altered forever how news is gathered and reported, and in so doing, has altered how world leaders and we, the public, receive and use news.

This pop-culture revolution has given us world-class and occasionally world-altering journalism, but also has led to silly, if not dangerous practices in the name of feeding the beast. Sometimes this has been an accident. Sometimes not. Think Of It as TV News 24/7: the good, the bad and the inevitable.

Among those profiled: Katie Couric, Ted Turner, Aaron Brown, Michael Stipe, Dennis Miller, Jon Stewart, Christianne Amanpour, Dan Rather.
