"PS3 unit sales were the highest of any month outside of that recorded during previous November and December holiday timeframes." Overall, the video games industry, including hardware, software and accessories, grew 53% in June to $1.69 billion, compared to the same month a year ago. Hardware sales were up 54% last month to $615.1million from the year before, while software sales grew 64% to $872.6 million during the month. Activision's ( ATVID) game Guitar Hero On Tour for Nintendo's DS took second (422,300 copies) while Ninja Garden II from Microsoft ranked third on the charts. Electronic Arts ( ERTS)> found itself placed sixth with its game Battlefield: Bad Company, while the last three of the top 10 spots went to Lucas Arts'Indiana Jones title.
