Through its video-game system, Nintendo has dominated a growing industry and has transformed itself into one of the world's most successful and influential corporations. The success of the Nintendo invasion is one of remarkable invention and marketing, but it also depends on a ruthless scorched-earth policy rarely seen in any industry. The company uses "whatever is required -- threats, intimidation, coercion." Nintendo has swallowed up the toy and electronic-game industries and has set its sights on the entertainment, consumer electronics, communications, and computer businesses.
