Cosa compra la pubblicità?

Visioni

Riccardo Puglisi
All'incirca metà dei ricavi dei giornali italiani proviene dalla pubblicità comprata dalle imprese. E i giornali trattano spesso di quelle stesse imprese nei loro articoli ed editoriali. Il fine dovrebbe essere quello di informare il lettore, ma alcune domande si impongono spontanee: i giornali trattano in maniera diversa le imprese che comprano pubblicità su di loro? Quanto contano i legami di proprietà tra imprese e giornali? I risultati di una recentissima ricerca empirica sul tema.
