A new archive is trying to digitize thousands of hours of tape from TV and radio stations across the country—before those tapes disintegrate. "The scary thing about it is that they are on physical formats that are deteriorating," Karen Cariani, director of WGBH's library and archives told me. "Video tape and audiotape is not a stable format. After 40 or 50 years, they are disintegrating. And the information—pictures, sounds on that physical medium—is disappearing. Unlike a piece of paper or a photograph that might last 100 years, media formats are extremely fragile."
