Along with measures the the Shanghai Metro has taken to ban eating and drinking on the subway (which passengers have since systematically ignored), another regulation has been set in place restricting TV channels from broadcasting long, repetitive advertisement.
According to Want China Times, the national TV watchdog announced that only one shopping advertisement could be shown during the 6 p.m.-12 a.m. time slot and it must be limited to three minutes in length. Further, videos advertising the same product cannot be advertised more than three times per day.
Probably just making more room for appropriate content (not that people on the metro generally bother to observe anything going on in the immediate vicinity unless it’s plugged into their headphones).
