Tubegazing: News Wars

News Wars (PBS, Tuesdays, beginning Feb. 13, 9 p.m.)

Journalists are under attack from hostile governments – including our own – and the changing demographics and economics of the digital age mean that all news gathering is undergoing the most radical changes in modern times. In this four-part series, "Frontline" looks at everything from the Valerie Plame leak to the role of blogs and the impact of entertainment on news. As Ted Koppel says, judging news by the same standard as entertainment may be the greatest tragedy in the history of journalism. Grade: A
