European developments 

In November 2014, Facebook announced a global revision of its data policy, cookie policy, its terms and conditions. Following this announcement, the Data Protection Authorities of Belgium, France, Hamburg, Spain and the Netherlands joined forces to create a Contact Group. Members of this Contact Group have since been investigating the revised policies of Facebook by for example exanimating the validity of consent given by data subjects and by reviewing the processing of personal data carried out by Facebook for advertising purposes. On 16 May 2017 several Data Protection Authorities published an common statement towards Facebook Group.
