About Sega Genesis

The Sega Genesis, known as the Mega Drive outside North America, is a 16-bit fourth generation home video game console developed and sold by Sega. It was Sega's third console and the successor to the Master System. Sega released it in October 1988 in Japan as the Mega Drive, and in August 1989 in North America as the Genesis. In 1990, it was distributed as the Mega Drive by Virgin Mastertronic in Europe, Sega Ozisoft in Australasia, and Tectoy in Brazil. In South Korea, it was distributed by Samsung Electronics as the Super Gam*Boy and later the Super Aladdin Boy.

Hardware revisions

  • Model 1(1988)

    original launch hardware ('Genesis Model 1' with 'High Definition Graphics' badge), separate Power Base Converter for SMS support, EXT port for the (cancelled) Mega Modem, the only model that handles the analog YM2612 sound chip's true output — collector-prized for FM audio

  • Model 2(1993)

    cost-reduced redesign, slightly different audio output (collector debate about which sounds 'better'), more reliable

  • Model 3(1998)

    cheaper plasticky redesign, no headphone jack, no expansion port

  • Nomad(1995)

    portable Genesis with composite TV-out, ~3 hours on 6 AAs (poor battery life)

  • Tectoy Mega Drive 4(Brazil)

    built-in games with HDMI output (modern production)

Reception & legacy

Launch reception

Strong — Sega's aggressive 'Genesis Does What Nintendon't' campaign and a 2-year head start over the SNES gave it real competitive footing in NA

Notable controversies

Mortal Kombat blood-code controversy (1992 SNES had sweat, Genesis had blood, contributed to the 1993 congressional hearings and ESRB creation); Sonic 2 'Sonic 2sday' simultaneous worldwide launch (1992) was a landmark marketing innovation

Cultural significance

Sega's commercial peak; nearly tied Nintendo in NA during 16-bit era; Sonic established as cultural icon; the 1993 congressional hearings prompted by Genesis-vs-SNES Mortal Kombat directly created the ESRB rating system
