The European Communication Monitor 2023 (ECM) Report provides an overview on the field’s changing status and on emerging or disappearing trends over more than 15 years. It presents and interprets data from almost 40,000 respondents in 50 countries collected in surveys between 2007 (when Twitter took off) and 2022 (when ChatGPT entered the scene). A look back at the most important strategic issues over the years is combined with a look ahead to identify five areas of action for communication leaders and develops 15 theses based on summarising longitudinal empirical insights and current research literature. Dynamic developments in the fields of media, technology and public opinion building have transformed societies across Europe since the beginning of the 21st century. This has also changed the way companies, non-profits, governmental organisations, and agencies working on their behalf communicate with internal and external stakeholders. Professionals working in the field called strategic communication, corporate and organisational communication, public relations, or communication management face many challenges and see even more opportunities to leverage their expertise. The ECM is an international research project by leading universities in the field, organised by the European Public Relations Education and Research Association (EUPRERA) and the European Association of Communication Directors (EACD) supported by premium partner Cision as well as partners CECOMS, #NORA, and Fink & Fuchs. The study series generates insights that stimulate practice, support theory development, and guide education in universities across the continent. Additional knowledge has been gained through parallel studies in Latin America, North America and Asia-Pacific.
