The NBC series Superstore is already a couple of seasons on air.
The superstore used for the pilot actually exists. A branch of Kmart in Burbank, California, USA was used for both the exterior and interior shots. The typical red of Kmarte was specially changed to the blue of Cloud 9. The store even remained open during the shooting so that customers could watch the shooting live. After the first season had been ordered, the superstore was rebuilt in the studio and the Kmart branch was dismantled. The replica was located in Stages 22 and 23 of Universal Studio Hollywood in Universal City, CA, USA. The set was mostly destroyed by a tornado in the final episode of the second season and then demolished. The whole thing was part of a Universal Studios rebuild plan. The third season was filmed at Stage 16 and 17.
