Forty years ago, “Vietnam: A Television History,” the 13-part documentary series examining the Vietnam War, premiered on PBS. It served as a searing look into the background, cost and toll taken on the principal figures involved in the war, both at home and abroad. Judith Vecchione served as one of the producers on the series and joined Alec to speak about what went into creating such a wide-ranging and deep investigation of the conflict. The Emmy- and Peabody-winning Vecchione has served as an executive producer with Boston-based PBS station WGBH for the past 23 years, working on many ground-breaking projects, including the Civil Rights series “Eyes on the Prize.” Vecchione shares with Alec the weight of responsibility she felt in bringing “Vietnam: A Television History” to the public, what inspires her dedication to the important stories she produces, and how she mentors the next generation of documentary filmmakers.
