Halo 3, in a total massacre of the entertainment industry, successfully sold enough units to bring in $300 million to Microsoft. Announced today by Microsoft, and touched on by big-wig Bill Gates, Halo has successully accomplished the biggest first week sales numbers in the entire entertainment industry. By that I mean that no movie, CD, or other videogame has ever generated as much money as Halo 3 did in its first week. To put this into perspective for you Spider Man 3, this summer's highest grossing movie, ended with $336.5 million in sales. The difference here is that Halo 3 sold just shy of that number in the first week. Also of note, according to Microsoft, more than 2.7 million gamers played Halo 3 over the internet in the first week.
