David Fanning has been executive producer of FRONTLINE since its first season in 1983. In 2007, after 24 seasons and more than 485 films, FRONTLINE remains America's only regularly scheduled investigative documentary series on television. The series has won all of the major awards for broadcast journalism, including 32 Emmys, 22 duPont-Columbia University Awards, 12 Peabody Awards and nine Robert F. Kennedy Journalism Awards. In 1990 and in 1996, FRONTLINE was recognized with the Gold Baton -- the highest duPont-Columbia Award -- for its "total contribution to the world of exceptional television." In 2002, the series was honored with an unprecedented third Gold Baton for its post-Sept. 11 coverage, a series of seven hour-long documentaries on the origins and impact of terrorism. In 2003, A Dangerous Business, a FRONTLINE/New York Times joint investigation of the cast-iron pipe-making industry was awarded the Pulitzer Prize for public service. And in 2007, the series won a Special Emmy Award for Excellence in Television Documentary Filmmaking.

Fanning began his filmmaking career as a young journalist in South Africa. His first films, Amabandla AmaAfrika (1970) and The Church and Apartheid (1972), produced for BBC-TV, dealt with race and religion in his troubled homeland. He came to the U.S. in 1973 and began producing and directing local and national documentaries for KOCE, a public television station in California. His film Deep South, Deep North (1973) was a PBS/BBC co-production and the first in a long succession of collaborations between U.S. and European television. In 1977, Fanning came to WGBH Boston to start the international documentary series WORLD. As executive producer, he produced and presented more than 50 films for PBS in five years. With director Antony Thomas, Fanning produced and co-wrote Death of a Princess (1980). Then in 1982, again with Thomas, he produced Frank Terpil: Confessions of a Dangerous Man, which won the Emmy Award for best investigative documentary.

In 1982, Fanning began the development of FRONTLINE. The series has worked with well over 200 producers and as many journalists, covering a wide range of domestic and foreign stories. Its signature has been to combine good reporting with good filmmaking. Reviewers and critics have been lavish in their praise, calling it "the most consistently important weekly hour on television" (Cleveland Plain Dealer) and "one of the most distinguished in television history" (The Philadelphia Inquirer).

With Fanning's enthusiastic encouragement, one of FRONTLINE's singular achievements has been its embrace of the Internet. In 1995, FRONTLINE developed one of the first deep-content Web sites in history. By putting interviews, documents and additional editorial materials on its Web sites, the series made its journalism transparent and changed the nature and content of broadcast journalism. Rather than an ephemeral one-time transmission, the documentaries and all their ancillary materials are now preserved on the series Web site. And, as of 2007, there are more than 65 hours of full-length documentaries streamed on the series' Web site, one of the largest sites of its kind. "This is the great promise of public media," says Fanning. "This is where we hold our work for the future, our public library, our contribution to the intellectual commons."

In 1987, Fanning created the PBS series Adventure, which ran for five seasons and aired 50 programs. With adventurers Lorne and Lawrence Blair, Fanning produced Ring of Fire, an epic four-part travel series that explored the Indonesian archipelago. The series produced films with travelers and writers from Peter Mathiessen to Gerald Durrell.

In 2001, Fanning's determination to bring more foreign stories to American audiences led to the creation of FRONTLINE/World, a television magazine-style series of programs designed to encourage a new, younger generation of producers and reporters. The emphasis has been on bringing a largely unreported world to viewers through a series of journeys and encounters. Like its counterpart series, FRONTLINE/World has made a deep commitment to its Web site (www.pbs.org/frontlineworld/), offering original Web-exclusive video and reporting by graduate journalism students and an international network of correspondents. Fanning sees it as a prototype for the future, and a place to build a community of enterprising journalists.

In 2004, Fanning received the Columbia Journalism Award, the highest honor awarded by the faculty of the Columbia University Graduate School of Journalism, recognizing "Singular journalistic performance in the public interest ... David Fanning and his signature program, FRONTLINE, have turned a commitment to probing journalism and public service into an enduring national conversation, without which far too many important issues would remain veiled or hidden altogether."

Fanning and his wife, the television writer and producer Renata Simone, live in Marblehead, Mass.
