K-drama seems to be more popular across wider age ranges
More people regardless of age(except maybe teens/children/high schoolers/university students[?]) watch k-drama than listen to kpop, eg. my mom watch(-es/ed) kdrama for a period of time until a few yrs ago when she stopped watching TV n then after tat only went on facebook/reads the newspaper.
More people in Asia watch kdramas daily or weekly than listen to or follow kpop. Mostly, i think but am not sure, they casually watch(there might be fans/stans of shows/actors tho) cause its on TV (dubbed into local Asian language or subtitled).
Ppl not in Asia might not know how widespread kdrama became after early 2000s, the shows Autumn in My Heart and Winter Sonata continued or started the trend of mostly women viewers throughout many parts of Asia/🌏 who were devoted to kdramas' unique aspects; ofc not everyone continued all the while but some did and new viewers picked up where others left off.
I think the number of viewers of kdramas[even among men tho not as much as women now or then] hv risen (in Asia/🌏) than any other form of entertainment(I'm exaggerating but maybe not much).
Counting the number of hours watched daily/weekly across the world(on tv/dvds/streaming/mobile phones/pcs/maybe even on playstations/consoles) it probably dwarfs other countries shows(individually) but maybe video games in total are the only thing close or hv more hours played/consumed[streamed/reacted to] than kdramas(considering the opposite demographic tat consumes kdramas/videogames n the little overlap I assume between the 2)
At least tats my impression here in S.E.A.(tho awhile ago I read in a book from 2021 by a Korean american about Korean imported shows in America; probably/either in the 90s/2000s/2010s-so it's not just in Asia only)
