Call of Duty: Mobile may not capture all of the headlines that the full Call of Duty releases do, but it nonetheless has accumulated a huge audience. Activision has announced that the game has passed 500 million downloads across mobile platforms since its launch in October 2019.

This is an enormous number of players in comparison with the console entries, which generally top out around 30 million in sales. Unlocking that many more players is likely a huge reason why Activision pursued a mobile Call of Duty at all, as it has undoubtedly brought in millions of new people to the series.

It's also been very lucrative for the company. As Activision revealed in its earnings call, the free-to-play game has brought in over $1 billion since its launch from in-game transactions. Its rate of growth may actually be accelerating, too. It took a year for the game to cross 250 million downloads and reach $500 million in revenue; it took just six months to double those numbers again to their current values.
