Because the characters on SEAL Team are sent on missions around the world, usually to the Middle East, it is impossible for the show to actually send the cast and crew to these remote locations. Since most of scenes are set in the Middle East, the northern Los Angeles County, where the dry mountains take over the landscape, turns out to be an amazing location for SEAL Team to use as its backdrop. Working in the Los Angeles area has allowed for SEAL Team and the other military dramas to bring extra jobs to Hollywood. Other than using the locations in Los Angeles, because the shows typically have high pyrotechnics, specialists and companies have been getting work on the show. By bringing work to the Los Angeles area, SEAL Team’s producers are able to help the local economy and decrease expenses.
Because of the world series this week, SEAL Team had the lowest viewership with 4.67 million viewers and a 0.7 Adult 18-49 rating. Another reason the series had its lowest ratings is because the show was a re-run. CBS also decided to air a re-run at 10 pm. This airing had 3.37 million viewers and a 0.6 rating.
