While browsing for archival audio on the internet one night, radio historian J. David Goldin noticed a 1937 radio interview of baseball great Babe Ruth for sale on eBay. Goldin was startled; it looked almost exactly like the master copy he had donated to the National Archives more than 30 years ago. Goldin started sleuthing. His detective work set in motion an investigation that revealed one of the most serious thefts in the history of the National Archives. In stealing those master copies, the culprit stole history, a trove of mind-blowing audio recordings spanning decades of American culture. These audio recordings mark an age before television and the Internet, when only sound connected you to the rest of the world. Host John Hockenberry wonders, how does audio transport you back in time better than a photo?
