Retail and Digital Sales Almost Equal

We like to keep an eye on the PC platform at GameBanshee, and as such this report from NPD is interesting (keeping in mind NPD is USA only and uses highly inexact methods).
The group said that games sold at retailers were down on YoY revenue, but still sold 23.5 million compared to the 21.3 million sold online via platforms like Steam, D2D and more.

NPD also said that sales of digital downloads for PC (represented) nearly half of unit sales across all download and retail last year, with it sharing 38 percent in revenue.
