A Brief History of TWICE: From Survival Show to Global Stardom

TWICE’s story began in 2015 with the reality survival show “SIXTEEN”, where 16 JYP trainees competed for a spot in the final lineup. The show was intense, but nine trainees—Nayeon, Jeongyeon, Sana, Jihyo, Mina, Dahyun, Chaeyoung, Tzuyu, and Momo—emerged victorious, forming TWICE. Their name, suggested by JYP Entertainment’s founder Park Jin-young, symbolizes their mission to touch fans’ hearts “twice”—once through the ears (music) and once through the eyes (performances).

They officially debuted on October 20, 2015, with the mini-album “The Story Begins” and the lead single “Like OOH-AHH”, becoming the first K-pop girl group to achieve a “perfect all-kill” (topping all major Korean music charts) with their debut song. Since then, TWICE has released over 30 singles, multiple albums, and even Japanese releases, solidifying their status as K-pop queens.

Their journey includes:

  • 2016: First music show win with “Cheer Up”, which became a national hit in South Korea.
  • 2017: First full album “Twicetagram” and Japanese debut with “#TWICE”.
  • 2018: First dome tour in Japan, making them the fastest K-pop girl group to achieve this feat.
  • 2019: U.S. debut with “Fancy You” and sold-out world tour.
  • 2020-2023: Multiple chart-topping comebacks, including “More & More,” “I Can’t Stop Me,” “The Feels” (their first English single), and “Talk That Talk”.
  • 2024: Renewed contracts with JYP, confirming their long-term future as a group.

With a discography spanning K-pop, J-pop, and English songs, TWICE has proven their versatility and staying power in an ever-evolving industry.
