When PBS's "Frontline" airs "The Persuaders [3]," a new documentary exploring the marketing and advertising industry, you won't be seeing public relations executives explaining their work on camera. The program, which airs November 9, "intended to have a PR focus, but PR executives refused to 'go public' about what they do, Justin Vogt, a producer at 'Frontline,'" told the trade publication O'Dwyer's PR Daily [4]. O'Dwyer's reports that its staff "met with three 'Frontline' producers earlier this year, and provided a list of top executives for the program to contact. 'They were very informative, but would only speak off-the-record,'" Vogt told O'Dwyer's.
