bq. Drawing from more than 25 hours of oral history interviews, Dr. Glenda Balas of the University of New Mexico has written and produced “The Long Road to Decatur: A History of Personal Influence.”
bq. The video documentary chronicles the development of the classic (and controversial) book _Personal Influence: The Part Played by People in the Flow of Mass Communications_, first published in 1955.
The webpage of the documentary, with a video file to download, is here. I haven’t yet watched the video. The book is still in print. Here is a critique of how the book’s findings have been interpreted.
