The Public Broadcasting Corporation has announced that they will be allowing access to hundreds of hours of their programming online, including such programs as the American Masters series with dazzling profiles of giant figures in 20th century entertainment as diverse as John Ford, Gene Kelly, Leonard Bernstein and Duke Ellington. Other shows, such as the recent retrospective You Must Remember This: The Warner Brothers Story, are expected to be online soon.
From a New York Times Bits Blog report on this development:
"There’s a lot of programming on the new site, including several years worth of episodes of many PBS programs including 'Frontline,' 'Nova', 'The American Experience,' the 'Newshour with Jim Lehrer' and 'Antiques Roadshow,' the highest-rated show on the network. Cooking fans may enjoy a library of the Julia Childs' shows, [...but some programming will not be online]. For example, much of the programming on 'Masterpiece Theater' is owned by the BBC, which will allow shows to be available on PBS.com for only a few weeks."
