Agents of S.H.I.E.L.D. is a television series that aired on ABC in 2013.
 During the summer months of June through roughly mid-September, network schedules typically feature reruns of their flagship programs, first-run series with lower rating expectations, and other specials
 Canadian shows do not normally receive "back nine" extensions within the same season, however; even a popular series simply ends for the year when the original production order has finished airing, and an expanded order of more than 13 episodes is applied to the next season's renewal order rather than an extension of the current season
