75% of GameStop purchases come from top 5 publishers
Nintendo, MS, Sony, EA and Activision account for huge majority of new product sales
The top five game publishers accounted for 75 per cent of GameStop's new product purchases in the 2010 fiscal year, according to the retailer's annual report.
GameStop said that Nintendo, Microsoft, Sony, EA and Activision products took a three-quarters share of sales - a figure up from 71 per cent the previous year, as reported by Gamasutra.
Nintendo took the highest percentage of the five companies with a 23 per cent share, down slightly from 25 per cent the year prior.
Sony increased its share from 13 per cent to 17 per cent, and Microsoft dipped slightly from 13 per cent to 12 per cent.
EA increased its share from 11 per cent to 12 per cent, and Activision grew from a more vague "less than 10 per cent" to 11 per cent.
The figures also revealed that the five subsequently sized GameStop vendors made up just 10 per cent of total purchases between them, while the remaining 15 per cent was divided between 65 companies.
GameStop's report added that its used game product business climbed by 18 per cent in fiscal 2010, while new game sales were up by one per cent.
In the year prior, used sales grew by 28 per cent, but new sales were up even further by 32 per cent.
GameStop's year-end financials, released in March, showed a drop in net earnings of 5.3 per cent to $377.3m.
