In today's cyber wars, the NSA (National Security Agency) has seized the throne. The NSA, formed in 1952, was originally tasked with monitoring foreign radio and television broadcasts and kept a low profile. After 9/11, however, the NSA worked closely with Homeland Security and the reach of its powers was greatly expanded.
Today, the job of the NSA ranges from wiretapping to internet monitoring to high-level encryption analysis. The NSA's infrastructure is classified, but they employ an estimated 30,000 people, operate four satellites, and use so much electrical power that they had to add off-site locations in Maryland to avoid constant blackouts.
