In his NPD preview for July game sales, Pacific Crest Securities analyst Evan Wilson looked back as well as forward. In tallying up the industry-tracking NPD Group's sales figures for the first half of 2007, Wilson noticed that first-party game sales are making up an increasingly larger part of the industry.
Wilson found that games published by Microsoft, Sony, and Nintendo represented more than 30 percent of total game sales revenue for the six-month period. He then compared it to the first six months of last year and the first six months of 2002 (like 2007, 2002 was the first full year after a transition to a new console generation). The analyst found that in each of those half-years, first-party game sales made up less than 20 percent of total game sales revenue.
