In the post-COVID era, explanatory journalism is undergoing a resurgence that can be attributed to the proliferation of false content disseminated via social networks and the maturation of fact checking initiatives. Fact checkers are beginning to delve into those topics that are recurrent targets of disinformation to make complex issues accessible to the public. This study investigates the characteristics and methodologies of contemporary explanatory journalism by analysing four European verification platforms (Newtral in Spain, Les Décodeurs in France, FACTA.news in Italy and The Journal FactCheck unit in Ireland). We employed content analysis of a corpus of explainers and semi-structured interviews with the managers of these outlets. Our findings reveal that explainers encompass a wide range of topics, typically revolving around current affairs. These pieces are usually authored by fact checkers and published, with bylines, within dedicated sections that encourage audience participation. Explainers do not adhere to a fixed periodicity or length and adopt a format similar to feature articles, displaying a degree of flexibility. They leverage data provided by experts and official sources and employ visual elements to convey information clearly. The interviewed managers concur that explanatory journalism represents an invaluable tool in combatting disinformation and has a promising future ahead.
