Both PlayStation 4 and Xbox One was reported to make more money than any of their predecessors in 2015, especially in the United States. From monthly sales report, it's known that the best-selling month was December last year. Although the sales hit a new record for the game consoles, it's nothing new that the Holiday season is the most competitive period of the year when it comes to games sales.

PlayStation 4 and Xbox One were both launched in November 2013. The two consoles embraced the Holiday season with a few console bundle offer deals. They sold the console along with the bundled game for as low as $299 during the Holidays, according to Geekwire. Now the prices have gone up again at $349 for each.

Both the consoles topped their predecessors' sales figures to a new record-high number of sales. To be precise, the combined cumulative sales of PlayStation 4 and Xbox One is greater than the combined sales of PlayStation 3 and Xbox 360 as their predecessors by 47 percent. The measure is accounted for within the period of 26 months, which is the time PlayStation 4 and Xbox One have been on the markets.

According to Venture Beat, up to October last year, the number of sales for PlayStation 4 and Xbox One only exceeded that of PlayStation 3 and Xbox One by 38 percent. But the percentage rose substantially starting November and went up until December. 

Although both the consoles are setting up record-high sales as to profit their different companies, competition did exist between the two. PlayStation 4, owned by Sony, outsold Microsoft's Xbox One to be the top-selling console in 2015, as reported by Game Rant. With the closing of the year, it's decided that Playstation outsold Xbox in ten months of the year. Xbox only beat PlayStation on April and October last year.

Sony CEO Kaz Hirai stated that the company has sold 35.9 million units of PlayStation 4 since it was launched in 2013. As many as 5.7 million consoles were sold during last year's holiday season alone.
The statement from Microsoft said that Xbox sales sustained 69 percent growth compared to last year's sale. In addition to the increasing sales, the total numbers of hours spent gaming on Xbox One worldwide also nearly doubled compared to December 2014.

In total, the game industry made $13.1 billion revenues from new hardware and software in the U.S markets. 2015 has been a huge year for gamers, and the prediction is that 2016 would also see a positive growth.
