Though World of Warcraft has always done huge digital business, the company has gotten a big boost this year from Call of Duty: Black Ops and its hugely popular DLC. As you can see in the chart above, this year's earnings are a big jump from 2010 and 2009, which respectively brought in $1.4 and $1.2 billion digital dollars.
Note: When Diablo 3 launches, Blizzard will be taking undetermined fees off the top of player-to-player items sales. So look out for the 2012 Analyst Day when Activision will have to use at least some of the digi-revenue to buy a taller chart.
