Sony has said that sales of its PlayStation 4 video game console exceeded 30.2 million units as of November 22, as global price cuts ahead of the year-end holiday season bolstered demand.

The PlayStation 4, which went on sale in late 2013, has been Sony's fastest-selling game console, the Japanese electronics manufacturer said. It hit sales of 20 million consoles in March.

The console helped Sony book its highest second-quarter operating profit in eight years.
