Microsoft's Xbox One may have trumped Sony's PlayStation 4 in terms of sales during the closing months of 2014, but it looks like the PlayStation 4 won the overall year.

According to Sony, the PlayStation 4 was the best-selling video game console worldwide last year and has tallied 18.5 million sales in the 14 months it has been available for purchase. The United States, in particular, has leaned towards the PlayStation 4.

"PlayStation 4 was the top-selling console in the U.S. and globally in 2014," a Sony Computer Entertainment America spokesperson told GamesBeat. "We are humbled by this success and want to thank gamers worldwide for helping us achieve holiday sales of more than 4.1 million across 123 countries and regions. We are looking forward to another momentous year in 2015 and bringing an epic line up of titles to PlayStation fans around the world."

Console gaming brings in around $50 billion in revenue, making it a lucrative market for both Sony and Microsoft, both of which now surpass the once-popular Nintendo as symbols of the gaming industry.

Sony's PlayStation 4 passed the 10 million mark during August 2014, making it fastest-selling PlayStation in history.

Those numbers, however, could change in the coming months.

Microsoft finished off November and December strong, beating out the PlayStation 4 during the busy holiday shopping season. Weekly sales, according to Microsoft, beat those of the Xbox 360 during the same point in its life cycle. Following a promotion that dropped the Xbox One's price down to $350, Microsoft announced that starting Jan. 16, all gamers can pick up an Xbox One for that same promotional price.

"Building off a record-setting holiday, we are excited to announce a new promotion in which fans in the U.S. can buy an Xbox One at a special price of $349, starting tomorrow, January 16, from their preferred retailer," said Mike Nichols, Corporate Vice President of Marketing for Xbox. "We are thankful for all the excitement for Xbox One this holiday and proud to offer more fans the amazing games lineup, Xbox Live gaming community, and continual innovation that Xbox One fans have come to enjoy."

Sony has not announced whether the company will follow suit and discount the PlayStation 4.

The latest iterations in gaming, both the PlayStation 4 and Xbox One have brought new technologies to the table, including the integration of touch screens, voice commands and visual recognition tools.
