After a tepid initial reaction, Quibi is keeping a close eye on spiraling costs, reports Bloomberg News. "Quibi has decided not to renew several shows from its first wave of programs, including Idris Elba’s Elba Vs Block," report Bloomberg's Lucas Shaw and Kelly Gilblom. "It has discussed ways of retooling others, said the people, who asked not to be identified because the plans haven’t been announced. Quibi also has preemptively scrapped shows that were meant to be shot later this year." Bloomberg also reports that one bright spot is that most people who start watching a Quibi show typically finish the episode. The reporters also point out that the two most popular shows on Quibi are The Rachel Hollis Show, hosted by the motivational speaker of the same name, and Chrissy Teigen's Chrissy's Court.
