"Momentum in mobile"
"Our fourth quarter results exceeded our prior outlook for both revenue and earnings per share," said Activision Blizzard CEO Bobby Kotick.
"Our recent Call of Duty success illustrates the scale of our growth potential, as we expanded the community to more players in more countries on more platforms than ever before."
"With our strong content pipeline across our franchises and momentum in mobile, esports, and advertising, we look forward to continuing to delight our players, fans and stakeholders in 2020 and beyond."
Candy Crush Saga continued to grow year-over-year to become the top-grossing title in the US App Store for 2019.
Furthermore, the franchise as a whole was the top-grossing across the same parameters in both the fourth quarter and full year.
