Düsseldorf is Germany's advertising and fashion capital. Agencies like Grey, Ogilvy and BBDO Düsseldorf shape data-driven marketing privacy, with a focus on cookie compliance, tracking, programmatic advertising and AI-based targeting. Corporations such as Henkel, Vodafone, Metro and Daimler Trucks bring classic corporate DPO requirements (BCR, group policies, joint controllership). The fashion sector (Esprit, Peek & Cloppenburg, C&A) processes extensive customer and employee data, often with international supply chains. In the telecommunications sector (Vodafone headquarters), the TKG and TTDSG supplement the GDPR with specific requirements for traffic data and location data.
