According to industry tracker NPD, sales of video game software and equipment in the United States fell 5 percent in May.
An analysis of product searches within the Video & Games category on Google Insights for Search also reveals a corresponding 5 percent decline in May.
In contrast product searches rose in May 2008 and stayed fairly flat in May 2009, suggesting this is not a seasonal trend.
Red Dead Redemption, the top game in May 2010 with 1.5 million units sold, was also the fastest rising search - up 1,150% month-on-month.
Nintendo Co Ltd's Wii was the top-selling home console in May, followed by Microsoft's Xbox 360 and Sony's PlayStation 3. Within product searches however, the Xbox was marginally ahead of the Wii, with the PS3 third.
