Not only was the Vietnam War a great factor in the turning of Americans' pride and trust in their country, it was also the last major event with emotional and political effect on the United States. Jean Picker Firstenberg, CEO and director of the American Film Institute, believes Sept. 11 might become the next.
"It took many years before we had films about the Vietnam War because that was such an emotional subject for so many people," she said. "But then there were a lot of movies that powerfully dealt with the topic -- it all comes with time."
More transitory is the effect of the new patriotism in the music industry, where a surge in the production of music about Sept. 11 has occurred. Soon after the attacks, however, the effects on music came from the buyers, not from the artists.
A number of artists saw some of their work released prior to the attacks being redefined in Sept. 11's patriotic aftermath. Americana-rocker Ryan Adams unwittingly found his breakthrough when single "New York, New York" found new listeners eager for a loving portrait of the battered city. U2's songs "Walk On" and "Peace On Earth" leapt onto the radio waves, the result of a desire for more reassuring pop music.
That people would turn to music for support is no surprise to Lawrence Grossberg, professor of communication studies at UNC.
"Music is a very important part of people's lives," he said. "Music is what they use to kind of live out their emotional lives, and 9/11 has been a traumatic experience for so many people."
But it didn't take long for artists to catch up to their audiences. Country musician Toby Keith saw his July album, Unleashed, debut at No. 1 on the Billboard charts on the strength of his unmistakably American single "Courtesy of the Red, White, and Blue (The Angry American)."
The July album from American rock icon Bruce Springsteen, The Rising, sat atop the charts for two weeks and is still in the top 10. The album deals with the grief and confusion of a post-Sept. 11 world, assuming the voices of survivors and victims.
"It is what Springsteen's fans expect him to do," Grossberg said. "They expect him to mediate the turmoil in their lives in his music -- it's what he does best."
But Grossberg is quick to point out that the albums have yet to enjoy long-term success and that the ultimate effect of their patriotic slants on their sales is unknown.
"Obviously more artists have included more patriotic songs in their work right now," he said. "But this is not a revolution in the music industry."
Something like a rebellion occurred in the world of pop fashion, however. In a rush to meet the public demand following Sept. 11, clothes with the American flag on them were prevalent in many stores.

"We had a bunch of different shirts on sale by October 1 -- from 'Remember Our Heroes' to 'United We Stand' T-shirts," said Piper Honigmann, manager of Franklin Street knick-knack boutique Lucky Stars.
Flagsoncars.com, a fund-raising Web site offering everything from flags, pins and car magnets to neckties, visors and skull caps with stars and stripes, was inundated with orders as the anniversary of the attacks approached.
"We've seen a 300 percent increase," said Lorraine Real, Flagsoncars.com vice president. "We have nothing to compare it to."
But Real is practical when considering the future of her enterprise."I do, realistically, think we'll taper off eventually," she said. "But I hope we'll continue."
There's little question that the newly popular patriotism will fade away sooner or later. The events of Sept. 11 will move into history and drift out of people's daily register. Pop culture has to, and will, move on.
But as long as there are crises, art will play its role.
"Art is the only way we can think through these times," Firstenberg said. "Art can show us the way."
