EEDAR, the company that said Sony's Welcome Back offerings were so successful that other companies should give old games away for free to promote newer offerings, has released its findings on the DLC market for 2011, confirming that more and more people are buying downloadable content. The company has discovered that 51% of the gaming market have bought DLC in the last 12 months, up from 40% last year.
The graphic above is a breakdown of their findings, including why exactly those that didn't purchase DLC held off from doing so.
Interestingly enough, despite the highest concern for non-purchasers being privacy, the PSN downtime has not really affected the percentage of people who don't feel safe putting their credit card details onto their console. The percentage, according to the report, has actually stayed pretty much the same, with the 360 suffering from a similar amount of people worried about their details.
EEDAR conclude that "release timing (releasing content earlier), marketing (increase in awareness of DLC), and lower wait times (increase in broadband speeds) are the primary drivers of growth in the DLC market."
