Title: Top Secret America
Content:  Top Secret America is a series of investigative articles published on the post-9/11 growth of the United States Intelligence Community. The report was first published in The Washington Post on July 19, 2010, by Pulitzer Prize-winning author Dana Priest and William Arkin. The three-part series, which took nearly two years to research, was prepared with the assistance of more than a dozen journalists. It focuses on the expansion of secret intelligence departments within the government, and the outsourcing of services. An online database, as well as the articles to be published, were made available to government officials several months prior to the publications of the report. Each data point was substantiated by at least two public records. The government was requested to advise of any specific concerns, but at that time, none were offered. The Public Broadcasting System featured Priest and Arkin's work on Top Secret America in a September 6, 2011 broadcast of the news documentary series Frontline.video That same month, the book Top Secret America: The Rise of the New American Security State was published by Little, Brown and Company.
