I recall when Sony Interactive Entertainment first released the PlayStation 4 in November 2013, there was a period of several months where demand out-stripped supply, and the console was out-of-stock in many places for some time.
Years have passed since then, and fortunately the stock issues are a thing of the past in most cases. The last three years have also seen the console go through the usual transition period, where most non-portable games developed for the PlayStation console are now being developed for the PlayStation 4, rather than just the PlayStation 3.
Citing sales data, Sony Interactive Entertainment have noted that a new milestone has been reached for the console. Although still nowhere close to the unit sales for the PlayStation 2 during its lifetime (Time will tell if it meets or surpasses its predecessor), the PlayStation 4 has sold 50 million units worldwide. This tally includes the sale of all PS4 models, including the recently released PlayStation 4 Pro.
