Activision Blizzard has added video-game competitor Electronic Arts to its $400 million countersuit against two former executives of "Call of Duty" creator Infinity Ward, claiming that EA tried to lure the executives away while they were still under contract with Activision.
Activision Blizzard's "Call of Duty: Black Ops" video game has raked in more than $1 billion in sales since its Nov. 9 release, making it the fastest-selling video game in history -- and one of the fastest-selling entertainment products of all time.
November delivered some welcome news for the gaming industry, with sales of consoles and games surging 8%. And Activision had plenty of reasons to smile as strong sales of Black Ops, the latest installment in the Call of Duty franchise -- earned it another spot on the list of best-selling video games.
