Snowden document reveals key role of companies in NSA data collection | World news | theguardian.com:

The key role private companies play in National Security Agency surveillance programs is detailed in a top-secret document provided to the Guardian by whistleblower Edward Snowden and published for the first time on Friday.

One slide in the undated PowerPoint presentation, published as part of the Guardian's NSA Files: Decoded project, illustrates the number of intelligence reports being generated from data collected from the companies.

In the five weeks from June 5 2010, the period covered by the document, data from Yahoo generated by far the most reports, followed by Microsoft and then Google.

Between them, the three companies accounted for more than 2,000 reports in that period – all but a tiny fraction of the total produced under one of the NSA's main foreign intelligence authorities, the Fisa Amendents Act (FAA).
