NSA paid tech companies millions to cover cost of PRISM compliance

Sourcing its story on files provided by whistleblower and former NSA contractor Edward Snowden, the Guardian reported today that the NSA paid millions to cover costs associated with PRISM compliance to tech companies including Google and Yahoo. The top-secret files referenced in the Guardian's report today amount to the first publicly shared evidence of a financial relationship between the US agency and internet service providers.

The costs in question were incurred after a 2011 FISA court ruling.
