The Washington Post reveals: "Two of the four collection programs, one each for telephony and the Internet, process trillions of 'metadata' records for storage and analysis in systems called MAINWAY and MARINA, respectively...The bulk collection of telephone call records from Verizon Business Services...is one source of raw intelligence for MAINWAY. The other two types of collection, which operate on a much smaller scale, are aimed at content. One of them intercepts telephone calls and routes the spoken words to a system called ­NUCLEON. For Internet content, the most important source collection is the PRISM project."
