kpop1-8, Exercise 1: Early spread in Asia

Model answer:

Breakthrough debuts named by the Korean Wave article (any two): BoA (2000), Rain (2002), TVXQ (2003), Super Junior (2005), BigBang (2006), Wonder Girls and Girls' Generation (2007).
BoA is credited as the first South Korean pop star to break into the Japanese market, with the album Listen to My Heart (2002), after barriers to entertainment trade between the two countries had fallen.
The article ties Hallyu 2.0 (from 2008) to YouTube because the second generation was driven mainly by K-pop distributed on online platforms like YouTube, and by social media.
It is a narrow claim because it concerns one market and one person; it does not say whether earlier Korean artists had tried before, so it means "first of the new wave", not "first ever".
