Update (3:15 p.m. EDT): Congratulations to the winners, including Philadelphia Inquirer, which won for public service reporting, Politico, which won its first-ever award for editorial cartooning, and The Tuscaloosa, for breaking news reporting.
Update (3:19 p.m. EDT): The Huffington Post newsroom is on its feet and clapping. Social media editor Rebecca Searles shared the below photo from just before the awards were announced. And Ahmed Shihabi-Eldin shared this video of the applause:
Bill Keller has got to be seething right now, after his spat with Arianna Huffington over aggregation last March. The New York Times picked up two awards, for explanatory reporting and international reporting.
Update (3:28 p.m. EDT): Congratulations to Sara Ganim, of the Harrisburg Patriot-News, who Piers Morgan Tonight producer Jonathan Wald points out is just 24 years old. She won local reporting for her coverage of the Penn State scandal.
Update (3:38 p.m. EDT): See our lede photo, a tweet from the Huffington Post's Joshua Hersh, of Pulitzer winner David Wood celebrating "The HuffPost way."
Update (3:54 p.m. EDT): We'll let the various newsrooms enjoy their champagne and Natural Light in peace. But one detail worth pointing out before wrapping up: The New York Times reports this is the first time in 35 years there hasn't been a winner for fiction. As Business Insider's Steve Kovach quipped on Twitter: "No one won a Pulitzer for fiction this year. Committee too busy reading The Hunger Games." Ha!
