Line is by Naver, South Korea's equivalent of Google. It is HUGE and while I don't doubt Google can afford it, it will cost alot. Kinda like Apple buying Samsung.On another note, different countries have their own popular chat app. Line is very popular in Japan even though it is done by a Korean company. In Korea, Kakao Talk is very popular. In China, WeChat is the popular one.
