Operating Metrics
The following operating metrics are key performance indicators that we use to evaluate our business. The key drivers of changes in our operating metrics are presented in the order of significance.
Net bookings and In-game net bookings
We monitor net bookings as a key operating metric in evaluating the performance of our business because it enables an analysis of performance based on the timing of actual transactions with our customers and provides more timely indication of trends in our operating results. Net bookings is the net amount of products and services sold digitally or sold-in physically in the period, and includes license fees, merchandise, and publisher incentives, among others. Net bookings is equal to net revenues excluding the impact from deferrals. In-game net bookings primarily includes the net amount of downloadable content and microtransactions sold during the period, and is equal to in-game net revenues excluding the impact from deferrals.
Net bookings and in-game net bookings were as follows (amounts in millions):
Net bookings
The decrease in net bookings for 2019, as compared to 2018, was primarily due to:
a $572 million decrease in Blizzard net bookings primarily driven by (1) lower net bookings from Hearthstone and (2) overall lower net bookings from World of Warcraft expansion and in-game content sales, primarily due to World of Warcraft: Battle for Azeroth, which was released in August 2018, with no comparable release in 2019 (although net bookings from subscriptions increased due to the release of World of Warcraft Classic in August 2019);
a $239 million decrease in Activision net bookings primarily driven by (1) lower net bookings from the Destiny franchise (reflecting our sale of the publishing rights for Destiny to Bungie in December 2018) and (2) lower net bookings from Call of Duty franchise catalog titles, partially offset by net bookings from Sekiro: Shadows Die Twice, Crash Team Racing Nitro-Fueled, and Call of Duty: Mobile, which were new releases in March 2019, June 2019, and October 2019, respectively; and
a $55 million decrease in King net bookings primarily driven by lower net bookings from player purchases across various franchise titles, primarily driven by the Candy Crush franchise, partially offset by an increase in advertising net bookings.
In-game net bookings
The decrease in in-game net bookings for 2019, as compared to 2018, was primarily due to:
a $539 million decrease in Blizzard in-game net bookings primarily driven by (1) lower in-game net bookings from Hearthstone and (2) lower in-game net bookings from World of Warcraft, in part due to World of Warcraft: Battle for Azeroth;
a $167 million decrease in Activision in-game net bookings primarily due to lower in-game net bookings from the Destiny franchise, partially offset by in-game net bookings from Call of Duty: Mobile; and
a $131 million decrease in King in-game net bookings primarily due to lower in-game net bookings across various franchise titles, primarily driven by the Candy Crush franchise.
