Even on state television gentle social satire about Saudi life is permissible and also welcome during Ramadan, a monthlong religious celebration when people pray, fast all day and then feast throughout the night. It’s a festive season that also serves as a sweeps month: TV ratings peak because people stay home and watch with their families, avoiding foreign shows to focus on Arab television. Especially in Saudi Arabia, which has the highest advertising rates in the Middle East, Ramadan prompts an avalanche of new dramas, comedies, talk shows and game shows. Because people are fasting during the day and obsessed with food, there are also lots of cooking shows, including “Saudi Chefs,” which stars two young, quirky alumni of “Top Chef Middle East.”
