The NPD Group has released its report on sales in the physical retail channel of the games industry during the month of July, with both predictable and surprising results. On the predictable side of things, all three segments (Hardware, Software and Accessories) continued their downward year-over-year decline, with total Hardware sales suffering a 34-percent decrease: $99.4 million this year as compared with $150.9 million over the same period in 2012.

Despite this industry-wide decline, Nintendo's 3DS saw a 14 percent year-over-year increase in sales as it held its spot as the best-selling piece of hardware for a third month in a row. This is the first time a handheld has topped the market for such a lengthy period since the Nintendo DS' three month streak in the fall/winter of 2010, according to NPD Group analyst Liam Callahan. Meanwhile, the Xbox 360 remained the best-selling home console for the thirty-first month in a row.

As per usual, the Accessories segment suffered the least amount of market fluctuation, experiencing only a three percent year-over-year loss and bringing in $133.4 million in sales. Also maintaining the status quo, this segment's stability continues to be attributed to steady sales of digital currency and subscription giftcards.
