You have to give Microsoft and Bungie some credit. They rolled out the hype thick and fast with Halo 3; the end result clearly outweighing the initial expenditure. In short, Bungie is laughing all the way to the bank.
According to Microsoft PR, more than 50,000 copies of Halo 3 had been sold and Australian consumers spent more than AU$6 million in just 24 hours. That makes Halo 3's debut the biggest first-day digital entertainment release ever in Australia.
