Sony proudly boasted that its PlayStation 4 game console has topped 18.5 million units sold since launching in late 2013.
There was high demand for the game console during the 2014 holiday shopping season, with 5 million units sold since the end of October. The PS4 suffered supply issues in Europe, so it's possible sales would have been even stronger ahead of Christmas if there was adequate inventory available.
Even though the Microsoft Xbox One has boosted sales in recent months, the PS4 continues to reign supreme. The Xbox One reportedly shipped 10 million units from late 2013 until November 2014 - and that doesn't equal actual consoles sold - with Microsoft not updating its numbers.
