On this day, thirty years ago, on the 21st of December 1994, Bungie Software released the action game called Marathon for the Macintosh line of computers. It went on to become a smash hit series, later followed by Marathon 2 (1995), Marathon Infinity (1996) and a number of fan-made expansions such as Marathon Rubicon, Marathon EVIL and several others.

Marathon’s and thus Bungies success laid the foundation for what was internally codenamed ‘Project BLAM’ which turned into the next success story of Bungie, namely Halo: Combat Evolved early in the 2000s, which led Microsoft to acquiring of Bungie with the intention of releasing the game solely for it’s upcoming X-BOX game console. Halo was however eventually released on both the Mac OS X and Windows as well.
