We don't know viewership yet, it's too early for that, though of course that's going to be enormous. Rather, the record in question is that Squid Game season 2 is the first series to debut at #1 in all 93 countries where Netflix is available. That's everywhere from the US, of course, to Cyprus to Honduras to Kenya to Oman to Thailand. The entire globe.
This simply doesn't happen. Even big shows that do well on global charts never debut simultaneously at #1 on the service, as some regions always prefer one series over another, however popular. But here this is a clean sweep for Squid Game, which is not something the original achieved as it took some time to go fully viral. But not Stranger Things, not Wednesday, not anything else.
