“Frontline” has streamed most of its documentaries free since 2002 (www.pbs.org/frontline), part of an effort to reach younger audiences than typically tune in to PBS. The online viewing to date of “Bush’s War,” which was broadcast in two parts on March 24 and 25, is an estimated “10 times the traffic of a normal show for us,” said Sam Bailey, the program’s director of new media and technology. Viewers are also sticking around much longer than they usually do on the site, typically for 7 to 10 minutes.

Viewers watching the documentary, which drew material from more than 40 past “Frontline” programs, also found an interactive, annotated timeline on terrorism over roughly three decades, including 175 embedded video clips and links to full transcripts of more than 400 “Frontline” interviews. The material remains archived on the site, along with many “Frontline” films.
