Retail and digital video game software sales over $33 billion in 2010 (VGChartz Ltd)
Retail and digital figures for tracked markets, seen below, came to over $33 billion in 2010, on over 3.2 billion game purchases. Overall, digital download revenues in 2010 totaled $2.5 billion representing 7.6% of the market total a figure expected to increase significantly over the next few years. In terms of unit sales, digital platforms (in particular Apple) are already dominating with only just over 20% of unit sales on Nintendo's Wii & DS, Sony's Playstation 3 (PS3), Playstation Portable (PSP) & Playstation 2 (PS2), and Microsoft's Xbox 360 (X360). Valve's Steam service took almost $1 billion in revenue in 2010 and is quickly approaching the size of some declining retail markets. With the remaining PC digital markets estimated at around $250 million in 2010, Steam dominates with nearly 80% of the overall PC digital market (results in chart 1).
