The Xbox Series X|S console platform is the fastest-selling Xbox of all time so far over a similar period of time in the market, with total sales reaching an estimated 6.5 million units.

　　For the period from launch until now, the Xbox Series X|S is the fastest-selling Xbox console family ever, Microsoft CEO Satya Nadella said on the company's earnings call today.

　　Niko Partners analyst Daniel Ahmad said his firm estimates that the total sell-in figure for the Xbox Series X|S is 6.5 million as of June 30. This is ahead of 5.7 million for the Xbox One and 5.0 million for the Xbox 360 over a similar period after launch. Ahmad also reminded people that, although the Xbox One shipped more units than the Xbox 360 in the beginning of its lifecycle, the Xbox 360 outsold it in the long run.

　　The sales achievements for the Xbox Series X|S--and the PS5, which is also the fastest-selling PlayStation console ever--are notable in part due to the ongoing chip shortages throttling supply.

　　We estimate that the Xbox Series X|S total sell in was 6.5m as of June 30, 2021.

　　Compared to our estimate of 5.7m for Xbox One and 5.0m for Xbox 360 in the same timeframe.

　　In other news, Xbox had a strong quarter, with total gaming revenue rising by 11%, or $357 million, for the period. Xbox hardware surged even more, by 172%, thanks in part to the Xbox Series X|S. Content and services, however, declined by 4% due to lower third-party game sales.

　　Xbox Game Pass, which is a key driver for the Xbox business, saw growth during the period, as did first-party game sales, Microsoft said.
