After 2016's Call of Duty: Infinite Warfare underperformed in the marketplace, Activision turned things around with Call of Duty: WWII this year. The game's initial launch sales far outpaced Infinite Warfare, and now Activision has announced that Call of Duty: WWII's global sales have amounted to more than $1 billion already.

In a year-end press release celebrating its achievements this year, Activision said Call of Duty: WWII and Destiny 2 are the No. 1 and No. 2 games of 2017 in North America based on revenue. Activision added that Call of Duty has now been the top-selling gaming series based on revenue for eight of the past nine years worldwide, and nine straight years in North America. Additionally, Call of Duty: WWII is the the "biggest console digital launch" in Activision Publishing's history.
