“…These operationalizations almost systematically consist of the following sequence of sub-components: (1) a quantity basedindex; (2) the characterization of the content; and (3) a time pattern. With respect to the first feature (i.e., quantity-based index), it appears that binge-watching is predominantly understood as the amount of episodes (n = 19) and programs (n = 1) [17, 18, 20, 21, 23-25, 28-32, 34**-40] or, more rarely, of hours spent viewing (n = 2) [22,23], comprising an underlying notion of multiplicity [18,21,27,30,31,37] or the genuine specification of quantitative cut-offs, ranging from watching more than 1 episode (n = 3) [17,20,28], to 2 episodes (n = 6) [17,23,25,32,35,40], and 3 episodes (n = 7) [24**, 29, 34**, 36, 38*, 39], or watching for more than 1 hour [23] [40], "in several days" [17,30], and "within a week" [39]. A graphical overview of these operational disparities across studies is provided in Figure 2.…”
