Some experts say that the Internet
is growing by an exabyte of data every day. To put that in
perspective, an exabyte equals 250 million DVDs.
After an exabyte comes a zettabyte, which equals 1,000 exabytes. In
2011, no single data center could hold a zettabyte of information.
By 2016, Cisco predicts that data centers will be sending more 1.3
zettabytes across the Internet every year. That's the equivalent of
sending all movies ever made across the Internet every 3 minutes.
The National Security Agency is building a $2 billion data center in
Utah that will be the world's first to store a store a yottabyte of
data. That's 1,000 zettabytes or 1 million exabytes (or 1 million
billion gigabytes).
Over half of Americans have watched TV streamed from the Internet.
