Documentary on Katz and Lazarsfeld's Personal Influence
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.”
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.
