Seven months after releasing Myth 2, at Macworld in New York, Bungie shows the original Halo announcement trailer, which is running in real-time using OpenGL on a Macintosh computer. There had been rumors earlier in the year about a game people thought was code-named "Blam".

Steve Jobs originally stated Halo would be released "early next year" but there was no confirmation of this from Bungie's side.
