Sony said Wednesday that global sales of its newest PlayStation have surged past the 10 million mark in less than a year, a record for the Japanese electronics giant. The release of the PS4 in the United States and other markets has helped to improve Sonys fortunes after a disappointing response to the consoles predecessor, the PS3. The responses we have received for the PS4 systems unique gameplay experiences… along with its vast game portfolio, has been phenomenal, Andrew House, president and group CEO of Sony Computer Entertainment, said in a statement. The PS4 is locked in a battle for dominance of the digital home entertainment market with Microsofts Xbox One and the Wii U at a time when consoles are under intense pressure to prove their worth in a world where many now play downloadable games on smartphones and tablets.
