An excerpt from Livescience:

A common media myth that sprung up after the attacks was that American tastes in entertainment would be forever changed. After seeing real-life horrors, the experts claimed, Americans would yearn for non-violent, wholesome family fare. Pundits filled pages second-guessing America’s taste in entertainment—nearly all of which turned out to be overstated or flat-out wrong.

Entertainment Weekly magazine, for example, devoted much of its Sept. 28, 2001, issue to, as the cover put it, “The challenge to our culture.” The magazine joined in the media chorus talking about the death of irony and the dramatic impact terrorism would have on the entertainment industry. Writer Jeff Gordinier wrote that “it’s hard to believe that we’ll ever see anything the same way….it took only an instant of excruciating reality to render our old [entertainment] appetites moot, piddling, even nauseating.” The effect was so profound, Gordinier wrote, that “the mere glimpse of a quippy sitcom was enough to induce a sour grind of physical revulsion.”

That effect, if it was ever true, seems to have been short-lived.

Within months, American tastes in entertainment returned to “normal” and in fact grew even more gory, sadistic, and horrifying than before 2001. “Torture porn” films such as “Saw” and “The Hills Have Eyes” were so successful that they spawned dozens of sequels and imitators. (“Saw,” which features victims being tortured to death in creative, sadistic ways, grossed more than $100 million in box office sales worldwide.) Quippy sitcoms are everywhere, and more Americans can name Britney Spears’s ex-husband than the prime minister of Iraq.

Claims that tragedies fundamentally change the American character are not new, of course. Similar pronouncements followed the Columbine shootings and the Oklahoma City bombing, as well as the 1993 World Trade Center bombing. Certainly, the September 11 attacks were of a different scale, but the “everything has changed” motif has been disproven over and over again.

Americans are much more resilient than they are given credit for.

America will always live with the legacy of the September 11 attacks, in myriad ways ranging from airport security to annual memorials. But there’s little evidence that the average American’s life or character has been changed forever.
