Sega first launched the Master System in June 1986 (US) — priced at $200 — to compete with Nintendo’s NES. Unfortunately, the system only managed to sell 125,000 units in its first four months, compared with 2,000,000 NES consoles sold in the same period. Video clips after the jump.

The system ultimately failed to oust its competitor, but has enjoyed over a decade of life in secondary markets, especially Brazil. By 1992, the Master System’s sales were virtually nonexistent in North America and production ceased.
