LINE has never had any significant market share in Korea, it's 100% Kakaotalk. LINE does have a large amount of development going on in Korea, however.

That's interesting. I recently noticed LINE showing up in a number of Korean shows on Netflix and I wondered how popular it was over there.

I wonder if it's actually an indication of how unknown it is. Korean media is usually very precise with showing brands - if you can see a logo it's almost definitely product placement. Using a relatively unknown app allows them to avoid showing something recognizable.

This is just an idea though, I have no real basis for the claim. I have noticed the same thing, though.

They prominently displayed the line characters, Brown and Cony in a message chat between the two main characters in 2015s "Hyde Jekyll Me" on Netflix.

I doubt you'd do that as a mean to show a generic chat. I think that is more of an attempt to make inroads in Korea (or perhaps pandering to viewers outside Korea)

It's a couple of years since I spent extended time there, but if there's anything I know it's that Koreans move fast, so I wouldn't be surprised if I'm slightly off there.

It's absolutely the case in Japan, though.

LINE is bigger than WhatsApp in Taiwan and I think Thailand, though.

I’ve never met anyone in Thailand or Taiwan who don’t use LINE.

It’s also my primary messaging app. What’s App is only used for business stuff in Singapore.
