Of course, the Pentagon has long poured U.S. tax dollars into private coffers to arm and outfit the military and enable it to function.  

At the time of Eisenhower's farewell address, New York Times reporter Jack Raymond noted that the Pentagon was spending "$23,000,000,000 a year for services and procurement of guns, missiles, airplanes, electronic devices, vehicles, tanks, ammunition, clothing and other military goods."  

Today, that would equal around $200 billion. In 2007, the Department of Defense's stated budget was $439 billion. Counting the costs of its wars in Iraq and Afghanistan, the number jumps to over $600 billion. Factoring in all the many related activities carried out by other agencies, actual U.S. national security spending is nearly $1 trillion per year. 

Back in Eisenhower's day, arms dealers and mega-corporations, such as Lockheed and General Motors, held sway over the corporate side of the military-industrial complex. Companies like these still play an extremely powerful role today, but they are dwarfed by the sheer number of contractors that stretch from coast to coast and across the globe.  

Looking at the situation in 1970, almost 10 years after Eisenhower's farewell speech, Sidney Lens, a journalist and expert on U.S. militarism, noted that there were 22,000 prime contractors doing business with the U.S. Department of Defense.  

Today, the number of prime contractors tops 47,000 with subcontractors reaching well over the 100,000 mark, making for one massive conglomerate touching nearly every sector of society, from top computer manufacturer Dell (the 50th-largest DoD contractor in 2006) to oil giant ExxonMobil (the 30th) to package-shipping titan FedEx (the 26th). 

In fact, the Pentagon payroll is a veritable who's who of the top companies in the world: IBM; Time-Warner; Ford and General Motors; Microsoft; NBC and its parent company, General Electric; Hilton and Marriott; Columbia TriStar Films and its parent company, Sony; Pfizer; Sara Lee; Procter & Gamble; M&M Mars and Hershey; Nestlé; ESPN and its parent company, Walt Disney; Bank of America; and Johnson & Johnson among many other big-name firms.  

But the difference between now and then isn't only in scale. As this list suggests, Pentagon spending is reaching into previously neglected areas of American life: entertainment, popular consumer brands, sports. This penetration translates into a remarkable variety of forms of interaction with the public.
