Activision announced today that Call of Duty: Ghosts generated $1 billion in worldwide revenue on launch day.
Activision specifically noted in its announcement that it "sold more than $1 billion of Call of Duty: Ghosts into retail stores worldwide as of day one," meaning the figure is made up of units sold to retailers and not necessarily sales to consumers.
By comparison, Call of Duty: Black Ops II needed 15 days to reach $1 billion in sales, though that figure included units sold to consumers and not only to retailers.
Citing data from Microsoft, Activision also announced that Call of Duty: Ghosts has moved to the top spot on Xbox Live as the most-played game this week.
On the Xbox 360, average play sessions for Call of Duty: Ghosts have been longer than Black Ops II or Modern Warfare 3 over the same period, Activision said.
Looking ahead to the game's release at launch for Xbox One and PlayStation 4, Activision Publishing CEO Eric Hirshberg said Call of Duty: Ghosts will be more successful than all others.
"This is the must have launch title for the next generation of consoles, and we expect Call of Duty: Ghosts to be the most successful launch title for the Xbox One and PS4 by a wide margin."
Call of Duty: Ghosts is GameStop's most preordered next-generation game, Hirshberg said, citing data from the retailer.
