With BTS representing the most used Tumblr tag for the entire year, Wednesday's (Nov. 28) kickoff to Tumblr's annual Year in Review proved K-pop's undying dominance on the platform while providing a deeper look at the scene's most popular acts telling even more interesting stories.

Billboard is proud to exclusively reveal the top 30 K-pop acts on Tumblr in 2018 with, once again, BTS and EXO leading a ranking that highlights the top boy bands, girl groups and solo stars on the scene.

Male groups make up a majority of the list with 19 of the 30 entries led by BTS, EXO, Stray Kids, Seventeen and GOT7. The second highest representation came from girl groups netting eight slots with Red Velvet, BLACKPINK, TWICE, LOONA and MAMAMOO leading the charge. Of these top-performers, Stray Kids and LOONA mark the only acts who made their official bows on the K-pop scene in 2018 -- a significant debut for such newcomers that speaks to Tumblr's place for early adopters and digital tastemakers.
