Sony recently revealed that the PlayStation 4 was already a profitable business — the company actually makes money on each PS4 console they sell. It took Sony just 6 months to get the PS4 into profitability, where as it took the PS3 over 3 years.

Now Sony has revealed that over 50% of the approximately 7 million PlayStation 4 owners worldwide are PS Plus members. Which isn’t a surprise, because PS Plus is required for online multiplayer and many other online features. That’s 3.5 million PS Plus subscribers in the first six months — not bad at all.

According to Sony’s Kaz Hirai, PS Plus is seeing a much higher attach rate than the PS3 did when the service launched on the PS3 back in 2010.

So far the PlayStation 4 has been a successful business proposition, as it’s already profitable, both hardware and software wise, and the online services are making money as well. This is important for Sony because the majority of its other business are losing more and more money each fiscal year.

Hopefully the trend will continue, although the PS4 will face tougher competition from the cheaper Xbox One starting next month.
