The Huffington Post won its first Pulitzer Prize on Monday.
The AOL-owned site announced that the series written by its senior military correspondent David Wood called "Beyond the Battlefield" won the internet publication its first Pulitzer.
The New York Observer noted that Wood, a former Time and Los Angeles Times reporter, had been a finalist in the past, and a win for The Huffington Post would go a long way in cementing its credibility.
Business Insider, which first leaked the rumor about the win, said it would be a second big win for AOL CEO Tim Armstrong after he sold 800 patents to Microsoft for $1 billion last week.
Wood won for the "National Reporting" category, with fellow journalism winners including writers at The New York Times, The Boston Globe and Chicago Tribune, among others. The complete list was posted on the Pulitzer website.

The Associated Press won a Pulitzer in investigative reporting for its series on the New York Police Department's surveillance of Muslim Americans.
The winners of journalism's most important prize were decided by a board made up of two dozen journalism academics and journalists. The winners were announced by Columbia University's Graduate School of Journalism, said The Washington Post.
Politico was the other "new media" website to win a Pulitzer in the editorial cartooning category.
