for a proper tv show i suppose it was squid game. though thats on netflix/internet so maybe american dad?
if you could consider anime then my hero academia was the last one. if not, either of the first ones i mentioned.
Would be Squid Game for me. First bit of Korean media I ever experienced and it was pretty good. I still need to get around to watching Train to Busan and Oldboy that have been on my "to watch" list for a while now.
