We spoke with Rick Sebak, a producer of favorite public television documentaries, via telephone from the Pittsburgh studios of WQED-TV. The mp3 podcast conversation can be downloaded here and can be enjoyed on your personal computer or loaded onto your personal mp3 player for on-the-go listening. You can also subscribe to our monthly podcasts via iTunes by clicking here. Sebak has produced and narrated a series of documentaries including A Hot Dog Program, Sandwiches We Like To Eat, An Ice Cream Special and Unusual Buildings and Other Roadside Attractions. Using a wry wit and finding normal everyday folks to tell the story of their local favorites -- from diners to cemeteries -- Sebak has created a successful style that is all his own. This month, Sebak offers his newest special, To Market To Market To Buy a Fat Pig. In the film, viewers are transported to various public marketplaces across the United States to see the local flavor. The program airs on WPT Wednesday Aug. 1 at 7 p.m. In our interview, Sebak talks about his history in public television, what he tries to accomplish with his documentaries and what his favorite market finds were.
