August 2015 NPD: PlayStation 4 and Madden are the kings of summer

You always know summer is over when you read that the latest Madden NFL is the top-selling game of August.

New physical games and hardware generated $548 million in spending at United States retailers last month, according to industry-tracking firm The NPD Group. That represents a 2 percent decline in revenue for the industry, which you can primarily pin on lower software sales despite a new Madden coming out — although hardware sales are actually down as well. Console gaming in the U.S. generates about $13 billion in spending.
