The SEGA Megadrive/Genesis is a fourth generation home console.
1st is Magnavox Odyssey, Pong consols, Colour TV games and so on.
2nd is Atari 2600, Intellivision and so on.
3rd is NES, Master System and so on.
4th is SEGA Genesis, SNES, PC Engine and so on.
I have heard of people combining the first two gens but that would cover a very wide mark of 1972 to 1983.
It's common to be confused by the Master System (Also known as the SEGA Mark 3 in Japan) as it was the third iteration of SEGAs SG-1000 8-bit consoles but the first to be sold overseas, therefore it was given a new name.
Also the SEGA Mark 3 was originally released in 1985 in Japan.
