Even while console and software sales across the industry have slowed, Microsoft's Xbox 360 continues to grow and remains on track to have the biggest year in Xbox history.

The console is in the sixth year of its lifecycle and was again the top-selling video-game console in the U.S. last month, bucking a software-led decline that saw industry sales slump 10 percent.

According to The NPD Group, an independent market research firm that tracks the digital entertainment market, consumers purchased 507,000 Xbox 360 game consoles in June. The company since 2005 has sold 48 percent of all current- generation consoles in the U.S., the research firm said.

Sony didn't release sales data for June.

Nintendo's Wii console contributed to a 10 percent decline in overall retail sales of $1.03 billion in June, NPD said. Nintendo claims to have sold 273,000 Wii consoles, 386,000 Nintendo DS handhelds and 143,000 3DS handhelds.

Industry hardware sales dropped 9 percent to $366.6 million, and software declined 12 percent to $469.5 million, NPD reported.

The top three console games in June were Rockstar's L.A. Noire, the Duke Nukem Forever from Take Two and inFAMOUS 2 from Sony. The remaining top 10 included Disney's LEGO Pirates of the Caribbean, Nintendo's Legend of Zelda: Ocarina of Time 3D for the 3DS, Call of Duty Black Ops from Activision Blizzard, Take Two's NBA 2K11, Warner Brothers Mortal Kombat, Disney?s Cars 2 and Ubisoft's Just Dance 2.
