Xbox One may have been outselling the PS4 in the US for the last few weeks, but for the month of October it was PS4 which ruled the roost.
"The results are in, and PlayStation 4 is the top-selling console in the US for October! Thank you!" tweeted Sony.
Neither Microsoft nor Sony have released actual sales figures, but on the whole, both systems are performing well, the NPD adds.
"October 2014 marks the first 12 months of sales for the Xbox One and PS4," NPD's Liam Callahan explained. "After the first year, these consoles have had a great start as cumulative sales are currently over 70 percent higher than the combined first year totals of Xbox 360 and PS3."
In October sales of Xbox One, PS4 and Wii U accounted for 80 per cent of spend on game related products.
Through the first 10 months of 2014, total sales of Wii U hardware increased by 47 per cent over the same period in 2013.
Software sales for the month were led by NBA 2K15, though Super Smash Bros. for 3DS has now sold 1.2 million copies across retail and digital (485,000 in October).
The Evil Within also performed well at No.3, recording the "highest-selling first month of sales for new survival horror IP".
Destiny drops down to fifth and Middle-earth: Shadow of Mordor is in ninth. There's no Top 10 spot for Sunset Overdrive as bundle sales don't count, but it would chart in ninth if looking only at single SKU sales.
