Nintendo Wii game console again managed to outsell both its rivals from Microsoft and Sony Computer Entertainment Inc. in May, according to data recently released by NPD Group. Not surprisingly, Microsoft Xbox 360 manages to outsell Sony’s PlayStation 3, while predecessor of the latter slowly loses popularity among gamers.

The lately released figures by NPD Group indicate that back in May Nintendo sold 338 thousand Wii consoles and 10 thousand GameCube consoles, Microsoft sold 155 thousand of Xbox 360 game machines, while Sony sold 82 thousand of PlayStation 3 and 188 thousand PlayStation 2 game consoles. Total market for non-portable game consoles was approximately 773 thousand units.

Total available market of non-portable game consoles was down slightly compared to April, which is inline with historical video game market trends.

Nintendo also dominates the market of handheld game console with 423 thousand of Nintendo DS and 80 thousand of Nintendo GameBoy Advance sold in May. Nevertheless, Sony also managed to increase sales of its PlayStation Portable to 221 thousand units.

The situation on the U.S. game console market has been stable in the recent months as previous-generation GameCube and PlayStation 2 gaming machines have been losing popularity. It should be noted, however, that both PlayStation 3 and Xbox 360 machines are also accepted by less and less people with only Nintendo Wii remaining fairly popular primarily among novices in video games.
