Through the study of the situation of popular publisher series that were born in France at the beginning of the 20th century (and whose mutations we will follow until the 1960s), we wish to highlight the relationship that exists between the interval (as a temporal and spatial characteristic of serialized goods), its media formulation in popular publisher series (through the question of periodicity and series), and a certain number of thematic, narrative and diegetic phenomena which result from it. Narrative and diegetic properties can only be understood in the broader framework of the media and market serialities at their origin since they are their poetic and aesthetic reformulation. Indeed, media practices have undergone significant transformations. These transformations corresponded to the new logic of standardization, serialization and brand enhancement induced by the new distribution scales; they accompanied the mutations of Taylorism and Fordism; finally, they characterized new American-style consumption practices that have reflected these changes. However, as we will show here, each of these transformations affected both the way of conceiving the texts (their poetics) and that of apprehending them (the aesthetic relationship that the works engage).
