According to a recent article, TWICE is one of the two girl groups that paved the way for the global expansion of K-pop girl groups:
“TWICE expanded the scope of their activities centered around large-scale performances. They demonstrated how much influence a K-pop girl group can have in the North American concert market. After building a local fanbase through continuous musical activities, they gradually increased the scale of their performances from arenas to stadiums, proving their ability to attract local audiences in North America.”
