Like rival Kun-Hee Lee of Samsung, Koo has added luster to the LG brand over the years. (Exhibit A: a Prada-branded cellphone.) LG's overseas sales soared to over $90 billion last year, with revenue up 25% to $122.4 billion. Koo has steadily built the group's flagship LG Electronics (LGE) into the world's second-largest maker of televisions, behind Samsung and ahead of Sony. Koo flexes his power in the boardroom too. In October of last year he replaced outgoing LGE chief executive Nam Yong with his brother, Bon-Joon Koo.
