Jacob Weisberg will remain editor of Slate, while its business operations will be run by Washingtonpost.Newsweek Interactive (WPNI), a subsidiary of The Washington Post Company. Cliff Sloan, vice president, business development and general counsel of WPNI, has been named publisher of Slate. Its offices in New York and Washington, DC will continue to operate.

Slate claims an audience of six million readers use the website as a primary source of news, information and commerce. According to the Washington Post, it has a similar audience to other WPNI publications (washingtonpost.com and Newsweek.com).

Donald E. Graham, chairman and CEO of The Washington Post Company, said: Slate has been a pioneer in internet publishing, and it is a fine magazine. Founder Michael Kinsley, editor Jacob Weisberg, and Microsoft deserve great credit for creating Slate. We couldn’t be more enthusiastic about this acquisition.
