Example Input: Context: The game is the first installment in the Forza series, a series that has continued on Microsoft's subsequent consoles, the Xbox 360 and the Xbox One. I Link Information: The Xbox 360 began production only 69 days before launch, and Microsoft was not able to supply enough systems to meet initial consumer demand in Europe or North America, selling out completely upon release in all regions except in Japan. Forty thousand units were offered for sale on auction site eBay during the initial week of release, 10% of the total supply. By year's end, Microsoft had shipped 1.5 million units, including 900,000 in North America, 500,000 in Europe, and 100,000 in Japan.
In May 2008 Microsoft announced that 10 million Xbox 360s had been sold and that it was the "first current generation gaming console" to surpass the 10 million figure in the US. In the US, the Xbox 360 was the leader in current-generation home console sales until June 2008, when it was surpassed by the Wii. The Xbox 360 has sold a total of 870,000 units in Canada as of August 1, 2008. Between January 2011 and October 2013, the Xbox 360 was the best-selling console in the United States for these 32 consecutive months.
In Europe, the Xbox 360 has sold seven million units as of November 20, 2008, according to Microsoft. In the United Kingdom, the Xbox 360 has sold 3.9 million units as of June 27, 2009, according to GfK Chart-Track.
While the original Xbox sold poorly in Japan, selling just 450,000 by November 2011, the Xbox 360 sold almost as poorly, selling 1.5 million units from 2005 to 2011. Edge magazine reported in August 2011 that initially lackluster and subsequently falling sales in Japan, where Microsoft had been unable to make serious inroads into the dominance of domestic rivals Sony and Nintendo, had led to retailers scaling down and in some cases discontinuing sales of the Xbox 360 completely. The significance of Japan's poor sales might be overstated in the media in comparison to overall international sales.

 Question: Which of Microsoft's gaming systems for which the Forza series was developed has sold the most units?
Example Output:
Answer: The Xbox One
