Following the House's vote to defund Public Broadcasting, the Corporation for Public Broadcasting posted this video of Fred Rogers testifying before Congress in support of some of the earliest Federal funding for public television.
That do-it-yourself determination to harness modern media for the public good is still alive and well in shows like Frontline—which just released the best report I've seen on the Egyptian revolution of 25 January. It's alive and well in NPR's Planet Money podcast, which started in the wake of the 2008 financial crisis and is now the reason I (mostly) understand mortgage-backed securities. It's alive and well in Radiolab, which is producing the best popular science reporting in any medium. And it's alive and well in On the Media, where even the question of Federal funding for Public Broadcasting is up for debate.
Want to keep Public Broadcasting alive and well? The Senate hasn't voted yet. And there's a website to get you started.
