On an average, which is the best source of revenue for a decently popular K-pop act? 38
-
Music - digitals/albums etc. (0) 0%
-
CFs - Modelling, Social Media endorsements (11) 29%
-
Acting - dramas, movies (0) 0%
-
Concert tours - Pre-Pandemic (25) 66%
-
Merchandise and other? (2) 5%
Just the best source of revenue to the "company". Without getting into how the company splits the money, distributes between one or more idols etc.
And irrespective of quantum of work, a CF might take only a day's worth of work, while a drama/movie make take months.
