After experiencing mediocre ratings on Fridays, ABC made several programming moves that resulted in the discontinuance of its Friday drama block after one season. In February 2018, ABC announced that "Once Upon a Time" (which had been experiencing declining viewership throughout its run, with its most noted declines taking place since its fifth season) would end after seven seasons. That May, the network cancelled "Inhumans" after one season, while giving another Marvel series, "Agents of S.H.I.E.L.D." (which replaced "Inhumans" for the 2018 midseason), a sixth season renewal for the network's summer 2019 schedule.
