US videogame sales extended their decline in February with a 25 percent monthly drop compared with a year ago, according to an industry tracker.

NPD Group said Thursday that total sales of hardware, software and accessories were $810 million in February, down from $1.09 billion 12 months earlier.

Videogame hardware sales were down a whopping 36 percent despite the launch late last year of the new version of Nintendo’s Wii console and PS Vita from Sony. NPD said Microsoft’s Xbox 360 was the top-selling device for the 19th consecutive month.
