Which entity is not a part of DG COMM?

In the context of EU communication structures, DG COMM refers to the Directorate-General for Communication, which is responsible for communicating the European Union's policies and activities to its citizens. It is primarily composed of professionals within EU institutions and entities that directly support EU communication efforts.

Private communication firms are typically not internal entities of the EU structure and thus are separate from the organization of DG COMM, which focuses on governmental communication rather than external commercial entities. National EU Communication experts and EU member state representatives are involved in crafting and promoting EU messaging, making them integral parts of DG COMM's operations. EU institutions themselves are at the core of DG COMM, as they form the foundation of the EU's communication strategies. Therefore, recognizing the composition of DG COMM helps identify that private communication firms are indeed not part of this internal structure, making them the correct choice for this question.
