At some of Samsung's Korean facilities you can find K-pop playing from speakers disguised as rocks, or a sign reading "Go! Go! Go!" in English, or old recordings of chairman Lee Kun-hee popping on and off of overhead loudspeakers in the halls. Samsung's culture, history, and rise into its major presence in the smartphone industry is profiled in a piece by Bloomberg Businessweek. Though the fun music and posters may paint the company's more playful side, it's all meant to instill a deep sense of quality control. "Samsung is like a militaristic organization," National University of Singapore professor Chang Sea Jin tells Bloomberg Businessweek. "The CEO decides which direction to move in, and there's no discussion — they carry out the order."
