Medal of Honor is a series of first-person shooter video games created by American film director and producer Steven Spielberg. The first game was developed by DreamWorks Interactive and published by Electronic Arts for the PlayStation in 1999. Medal of Honor spawned a series of follow-up games including multiple expansions spanning various console platforms and personal computers. The first twelve installments take place during World War II. The main characters are usually elite members of Office of Strategic Services (OSS), while later games focus on modern warfare. The concept, story, and executive production of the first three games was made by Spielberg, who later sold the franchise for Electronic Arts in February 2000. The music in the franchise was composed by Michael Giacchino, Christopher Lennertz and Ramin Djawadi.
