At the end of first half of 2007, the console stabilized at 11.6 million units shipped as sales dropped 60% while its rival, Wii, gained momentum and Sony announced a competitive price drop on the PlayStation 3. Microsoft's strategy to boost sales with the release of the highly anticipated "Halo 3" in September 2007 paid off, outselling the Wii that month in North America. Microsoft's Entertainment and Devices Division experienced a huge increase in revenue, largely driven by the release of "Halo 3", and posted a quarterly profit for the first time in two years.
