Which idol group other than SNSD heavily promotes in tv or variety shows?

??

I guess Super Junior

Can only think of 2nd gen groups like 2pm

I think IVE has been starting to do so.

Yujin has been everywhere when it comes to variety and the group has been joining her

ATM I don't think any group outside BTS has enough pull by the Korean audiences to warrant multiple TV appearances like SNSD or even their own show (BP could be a contender but they rarely go on shows in their career anyway).

Most groups do a couple TV shows, knowing Bros is almost always one of them, and the rest of the time is spent on music shows which works out well anyway.

SNSD was able to promote so much in variety shows because they have the pull and variety skills to do it. Knowing brothers, Game caterers PDs and hosts keep asking them to promise to come back

Aside from SNSD, I don't think there's any group that had the scale of variety shows that they did for their comeback this year
