According to a new Comscore study (users aged 15+, Dec 08 vs Dec 07). Good news for social games !
UK, Spain, Portugal, Denmark and Italy were the countries with the biggest penetration of social networking.
Also in the study : Facebook grew 443% in one year in France thanks to localization, and has now overtaken Skyrock.
The social networking landscape still remains pretty diverse in Europe – that isn’t shown in the study- but the overall usage is very high. For comparison, Emarketer recently published a similar study showing that the penetration rate was 41% in the US. That encompasses all year 2008 though, not just December as the Comscore figures.
