PlayStation 4 was the top-selling home console in December in the United States

Sony had another huge month to end the year.

PlayStation 4 was the best-selling home gaming system in United States, according to data from industry-tracking firm The NPD Group. Sony declined to comment on the sales, but the company did confirm the NPD data to GamesBeat. At the same time, Microsoft highlighted that December was also huge for its gaming division. The Xbox company also pointed out that PS4 sales slid year-over-year, and that Xbox One actually outsold Sony’s system in the second half of 2016. So while PS4 outperformed Xbox One in the last two months of the year, which are crucial to overall sales, the systems are a bit closer than they were in 2014 and 2015. Beyond the competition, however, the console gaming industry continues to contribute healthy revenues to the $99.6 billion gaming industry.
