Yes, however neither google nor facebook can be pinned down to a single product. They are now holding companies which own dozens of products, some of which are successful, some which are fads.

Ditto the Kakao and Line brands. Which are in turn operated by Daum and Naver - the two Korean internet giants. Google Maps for example is nigh on useless here: People use Naver Maps or Daum Maps. Line's principal visual identity is true to the mothership and uses "Naver green".
