As the world becomes more and more "flat," per se, exchanges and communications become astonishingly bidirectional. And hybrid products are born through this bidirectional "flattening," process as you easily find in all manufactured and cultural products. Korean entertainment producers are smart enough to know how to blend ingredients for universal attraction...Therefore, pop culture is speedily eroding boundaries of nations, as any multinational companies do.

The growing ranks of other Korean American performers recruited by management companies like SM Entertainment and JYPE in U.S.-based talent searches — aren’t just a random act of globalization. They’re the secret weapon in Korea’s next push for worldwide youth-culture domination.

"The spread of Korean popular culture is exceptional as it was not founded upon the traditional factors of military and economic dominance that characterized that of Western imperial powers, or the diaspora networks of India and China," said Liew, who has been tracking South Korean popular culture for almost a decade.

Korean policymakers are discussing the “Korean Wave 3.0.” The Korean Wave, or hallyu in Korean, means the export of Korean entertainment and other culture. The “Version 1.0” of the wave was the success of TV dramas and movies starting about 10 years ago. And “Version 2.0” is what’s been happening with K-pop music over the last year or so.

South Korea's government has been trying to change the country's international image - or rather its lack of one - for years. And even those involved - like Peter Kim, brand manager for the Seoul government - admit it has been a tough sell. South Korea's national branding is facing some unique challenges.

The fizzy, busy sound of Korean pop have conquered airwaves in Japan and China over the past few years, but this week marks the escalation of a campaign to charm American listeners. Whereas Utada and BoA presumed being big in Asia would equal sales in the U.S., Wonder Girls is being introduced specifically for the teen and tween markets.

Korea announced plans to promote Korean traditional culture on Monday. “K-drama started hallyu in 1995 and K-pop has been continuing its popularity since the mid-2000s. The recognition of Korean traditional culture, literature or other related sectors, however, is low. It is time to diversify the trend and make it sustainable,” said Culture Minister.
