If you have an iconic image on your hands, forget the front page: You're posting it on Facebook.。

That's exactly what the Associated Press did Monday, shortly after the assassination of Andrey G. Karlov, the Russian ambassador to Turkey. A young man shot the official to death at an art exhibit in Ankara, and the AP's Burhan Ozbilici captured the entire violent incident. 。

Less than two hours after the news broke, the AP's official account for images on Facebook shared a photograph of the gunman, arm raised in triumph, standing over Karlov's body.。

It spread rapidly, proving for the umpteenth time Facebook's incredible influence over how we receive information. That one AP post reached nine million people just six hours after it was published, according to internal metrics shared with。 Mashable  。Mashable。

that the photo post had 175 times the average engagement for the AP Images page. The company provided a graph showing how quickly the photo accumulated interactions — Likes, shares, comments and clicks on Facebook. You can see that it didn't take long to snowball:。 Credit: NewsWhip。By every measure, the photograph is a huge viral moment for the news outlet. Thousands upon thousands of people shared it with their friends in a few short hours, even though it clearly shows the body of a man who had been shot to death by a terrorist. A gut-turning act of violence, one we wish we'd never seen, became yet another bit of shareable content, wedged between status updates and other social ephemera.

"With those shares, the photo is surfacing on the News Feed of friends of whomever shared the post," Gabriele Boland, an analyst at NewsWhip, told。

. "Because of Facebook's algorithm that favors content shared by users over publishers and brands, more people are likely to see the photo in their News Feed. Then, they too may share it out, and the cycle continues."  。

That, for better or worse, is the media today: a startling photograph or article tossed onto your Facebook News Feed, perhaps by a doofus joking about a coldblooded murder.。

None of this is new, of course, but let's consider the context. Facebook has faced intense scrutiny in recent months for its role in distributing misinformation, hoaxes and other so-called "fake news." Despite its obvious role in distributing news, the company has consistently refused to acknowledge its responsibility as a media company, though last week it announced partnerships with third-party fact-checkers to battle the spread of "disputed" information on its platform.。 SEE ALSO:Facebook failed America this year — now it should kill the News Feed 。Reasonably enough, the conversations surrounding Facebook's responsibilities tend to focus on what's going wrong. "Fake news" is spreading. The company inadvertently censored an iconic photograph. Its algorithms create "echo chambers" where users comfortably shout their opinions to those who agree with them.。

One could argue about whether the photograph -- which is violent, disturbing and perhaps even glorifying -- should have been published at all, at least without a warning. (The。 New York Times。published an interview justifying its use of the image, saying, "The picture very clearly shows the shocking nature of the attack -- much more powerfully ... than a mere description.") Facebook let it stand, and then the site did its thing, spreading information across an intricate network of connected "friends" scrolling through their News Feeds.。

It's something of an apples to oranges comparison, but food for thought: Nine million people is considerably more than the print circulations of the Wall Street Journal and 。
