SAN FRANCISCO: US video game producer Activision Blizzard announced late Monday that it was buying King Digital Entertainment, best known for its ‘Candy Crush Saga’ mobile game, for $5.9 billion. Activision, whose games include the ‘Call of Duty’ series, said in a statement the purchase ‘will create one of the largest global entertainment networks with over half a billion combined monthly active users in 196 countries’. California-based Activision has some of the best-known video game titles on the market, including ‘World of Warcraft’, ‘Diablo’, ‘Guitar Hero’, ‘Skylander’ and most recently ‘Destiny’. Activision said it believes the addition of King’s business, which it called highly-complementary, will position it ‘as a global leader in interactive entertainment across mobile, console and PC platforms’.
