Washingtonpost.Newsweek Interactive was an online subsidiary of The Washington Post Company, headquartered in Arlington, Virginia, United States. WPNI operated washingtonpost.com, the website of the Washington Post, as well as the Web sites Newsweek.com, Slate, Foreign Policy Magazine, Budget Travel Online, Sprig, LoudonExtra.com, The Root and TheBigMoney. WPNI was formed in November 1993 under the name Digital Ink.
In 2009, Newsweek.com and Budget Travel Online were transferred to Newsweek (with Budget Travel magazine and Web site subsequently sold by Newsweek), and WPNI began doing business by the name Washington Post Digital. In 2010, WPNI ceased, and all employees transferred to The Washington Post or The Slate Group.
