Slate surpassed the 10 million mark in visitors for the first time in its history, according to comScore’s October traffic report. This audience number bests BusinessWeek.com, Bloomberg.com, and Wired.com and is more than TheAtlantic.com, Economist.com, and NewYorker.com combined.

“It’s been an incredible year for Slate,” said Jacob Weisberg, Chairman. “We’re thrilled to surpass 10 million readers and it been equally gratifying to see phenomenal sales growth.”

While traffic typically swells at most news sites during an election season, what makes Slate’s unprecedented number of visitors in October notable—an increase of 47% over 2011—is the mix of Slate features that were most popular. Slate’s sharp and insightful political coverage by Chief Political Correspondent John Dickerson and political reporter David Weigel, as well as innovative election coverage in video and infographics such as Political Kombat and Slate’s Electoral Map Challenge, received high billing. Yet Slate’s campaign stories were hardly the only subject readers were sharing and discussing in the social universe. Additional traffic was fueled by substantial conversations and sharing of Slate stories about technology, science, design, and women’s issues.

David Plotz, editor of Slate, added, “What makes this remarkable for Slate is that we’ve nearly doubled the number of stories we publish each day while maintaining the intelligence, insight, and wit we’re known for. We expected a surge of readers during campaign season, but it’s gratifying that we’re growing so fast in all sorts of subjects: technology, culture, business, science, and design.”

Advertisers matched readers’ enthusiasm for Slate during October with blue chip clients such as IBM, Boeing, Mercedes-Benz, Lexus, Volvo, Prudential, T. Rowe Price, Cap One, Wells Fargo, Chase Private Client and many others featured throughout the site. Through October, Slate is up 28% in advertising revenue over 2011.

“Advertisers recognize that Slate is the place to be for engaging editorial solutions and innovative branded content,” said Matt Turck, Publisher. “Our success during October and throughout 2012 is a promising bellwether for Slate into 2013.”
