WATCH: The Public Broadcasting Act turns 50. What’s changed?

Fifty years ago, the Public Broadcasting Act of 1967 created the vast public media system we know today.

How have things changed since then?

The Library of Congress and Boston public broadcaster WGBH are celebrating the 50th anniversary of the act with a series of panels exploring that question, including one on news and public affairs talk shows that featured PBS NewsHour’s Judy Woodruff, former anchor and executive editor Jim Lehrer and WETA CEO Sharon Rockefeller, as well as legendary talk show host Dick Cavett.

A collection of public media made possible by the act now totals 50,000 hours of preserved content, stored at the LIbrary of Congress in Washington, D.C., as well as at WGBH in Boston. About a third of those files, though, are available to consumers online. Explore them here.
