Salcedo revealed, and Gamasutra noted, that in the last 12 months alone Xbox Live had pulled in $180 million in revenue through online transactions.
According to their figures also, a game with DLC has seen a 16% percent longer time with their owner on average - "which keeps them from selling to secondhand stores."
"Right now we have over 12 million users in over 26 countries, with $240 million in transactions revenue so far, with $180 million in the last 12 months alone," said Microsoft's IEB manager Salcedo, giving a speech to attendees at Gamefest.
Interestingly a game would sell -- again, on average -- $21 million more at retail if its DLC would hit within a 30-day "sweet spot" of release.
