S.H.I.E.L.D. has been around since the 1960s, and the name has changed a few times
Debuting in a 1965 issue of Strange Tales, the agency S.H.I.E.L.D. was created by comic legends Stan Lee and Jack Kirby. The group has always represented a super-secret government spy agency, though the words within the acronym have been tweaked over the years. It originally stood for Supreme Headquarters, International Espionage, Law-Enforcement Division, and was changed to Strategic Hazard Intervention Espionage Logistics Directorate in 1991. It changed again when Marvel brought the agency to the big screen. Now, it’s known as: Strategic Homeland Intervention, Enforcement and Logistics Division. The group has almost always been headed-up by Nick Fury (played by Samuel L. Jackson on the big screen).
