Almost 217 million people worldwide visited online gaming web sites in May 2007, according to comScore’s World Metrix report. That’s up almost 17% from May 2006, and represents 28% of the total worldwide online population aged 15 and older. Bob Ivins of comScore said, “The fact that these web sites are pulling in over a quarter of the total worldwide Internet population shows what a global phenomenon gaming has become. The potential of the online gaming arena should be especially appealing for advertisers, as the average online gamer visits a gaming site nine times a month.” Yahoo! Games was the most popular property, attracting 53 million unique visitors, followed by MSN Games with 40 million. The fastest-growing Top 10 gaming property was WildTangent Network, a US company that makes online and downloadable games, which rocketed by 398% year-on-year to attract 11.5 million unique visitors in May 2007. The site attracted an average 12.2 visits per visitor, higher than any of the other top 10 gaming properties.
