The Big Three (The big 3):

These are the so-called big three entertainment groups in Korea, although this designation is very open to interpretation.

  • SM Entertainment (Girls‘ Generation, Super Junior, SHINee),
  • JYP Entertainment (TWICE, Wonder Girls, Miss A) and
  • YG Entertainment (BLACKPINK, 2NE1, Big Bang).

There is a debate on whether the „Big Three“ should be expanded to the „Big Four“ to include Big Hit Entertainment, which manages BTS and TXT, but many fans argue that Big Hit does not belong in the same category as SM, JYP and YG because it is a newer company and did not exist at the same time as the early days of the „Big Three.“

Fan Café:

The big three have discontinued their fan cafes in exchange for publishing content on their official websites.

V Live:

If you want to keep up with the idols, V Live is a must. This is a livestream platform where most K-pop idols have an official account.

This television show has recently been revamped, leading to a decline in its popularity, but it used to be considered the ultimate variety program where idols could show off their funny sides.
