The National Security Agency has obtained access to the central servers of nine major Internet companies — including Google, Microsoft, Apple, Yahoo! and Facebook. The Guardian and The Washington Post revealed the top-secret program, codenamed PRISM, after they obtained several slides from a 41-page training presentation for senior intelligence analysts. It explains how PRISM allows them to access emails, documents, audio and video chats, photographs, documents and connection logs. "Hundreds of millions of Americans, and hundreds of millions – in fact, billions of people around the world – essentially rely on the Internet exclusively to communicate with one another," Greenwald says. "Very few people use landline phones for much of anything. So when you talk about things like online chat and social media messages and emails, what you’re really talking about is the full extent of human communication." This comes after Greenwald revealed Wednesday in another story that the NSA has been collecting the phone records of millions of Verizon customers. "They want to make sure that every single time human beings interact with one another … that they can watch it, and they can store it, and they can access it at any time."
