Is there a point to spend money on teaser material for kpop releases anymore?

I'm pretty sure the teaser stuff is cheap. Usually it's just photoshop, costumes, and IMovie.

And i'm not sure if NJ is a good example of going cheap on teasers, they literally flew all the way to Spain and shot a crapload of content there. They musta had like 20 teasers, individual MVs, etc for Hybe Boy and Attendant.

I personally think teasers consume more time than money/budget; not applicable to all groups of course.

For me, a week of teasing is enough. I would just like to be teased about the album's mood and concept, get individual and group photos, a highlight medley, and one video teaser.

A month-long teasing is not a bummer for me also, but ONLY for comebacks after a long hiatus. Doing it for every comeback is nuts, JYPE.

I mean isn't MV teasers just cut out of an MV that is already going to be released

And samplers previews etc and cut out from songs that are going to be released anyway?

And photo teasers are from photoshoot that they already done anyways for the photobook?
