Who is Choi Gee-sung?

Choi Gee-sung is President and Chief Executive of the digital media division at Samsung Electronics, overseeing the third-largest business group of the South Korean company, which includes televisions, flat-panel screens, MP3 players, personal computers, and other consumer electronics. He was a New York City torchbearer for the 2004 Summer Olympics relay.

Choi had a stint as chief design officer and established Samsung's chip business in Europe in the 1980s. He's best known as a marketing expert, however, and is credited with having steered Samsung past Sony to become the world's No. 1 TV brand in 2006. Choi took over the running of Samsung's mobile phone business in January 2007. By September 2008, the company's global market share stood at 17.1%—second only to Nokia and up from 14.4% in 2007.
