Subparagraph 5.4.1 A Roles
75 For what concerns the determination of the roles of the different actors, the EDPB notes the following: in Example 7 in Section 5.4 , joint controllership exists between Museum Z and the social media provider concerning the processing of personal data for the purposes of targeted advertising, taking into account the collection of these data via the ‘like’-functionality on the social media platform, and the ‘analysis’ undertaken by the social media provider in order to offer the targeting criterion (“interested in impressionism”) to the targeter fitting the purpose of finally displaying the advertisement.
76 In Example 8 in Section 5.4, joint control exists between “bestpaydayloans” and the social media provider in relation to the processing operations jointly determined, in this case the selection of targeting criteria and subsequent display of the advertisement, as well as any reporting relating to the targeting campaign.
