Activision Blizzard has reported new financial numbers for the July-September period, and it was a gigantic quarter for the gaming publisher. One section of the company's business that did particularly well was microtransactions. For the three-month period, Activision Blizzard made $1.2 billion from microtransactions, which are called "in-game net bookings."

This is a dramatic 69 percent improvement over the same period last year, when Activision Blizzard made $709 million from in-game net bookings.

Microtransactions are very big business for Activision Blizzard. For the latest reporting period, Activision Blizzard made $1.95 billion in revenue from all of its business combined, so the $1.2 billion figure from microtransactions represents more than half of the company's total revenue.
