Sony Corp said on Wednesday sales of its PlayStation 4 video game console had exceeded 50 million units as of 6 December, helped by strong demand during the year-end holiday season.
The PlayStation 4, which went on sale in late 2013, has been Sony’s fastest-selling game console. It released in the US on 15 November 2013 and arrived on Indian shores in January 2014.
According to CNET the worldwide sales numbers includes the original PlayStation 4 model, the recently released slim PS4 variant as well as the new PlayStation 4 Pro. 
The slimmer PS4 is said to be more energy-efficient than PS4. It costs around $300, down from $350 for the previous version, and went on sale on 15 September earlier this year. The PlayStation 4 Pro costs around $400 and went on sale on 10 November abroad.
PlayStation 4 Pro offers 4K gaming, displaying hyper-realistic graphics and immersive visuals – as long as it is hooked up to a HDR, or high dynamic range TV.
“We’re truly delighted that the PS4 community continues to flourish since launch three years ago,” said Andrew House, president and global CEO of Sony Interactive Entertainment, in a press statement. “We will continue to provide the best gaming experiences available as we focus on accelerating our business and expanding the PS4 ecosystem.”
