RetroN5 Mega Drive
After its Master System lost the 8-bit war to the NES by some margin in the US, Sega wanted to make sure the 16-bit race was far closer. In order to get a headstart on Nintendo it released its 16-bit Genesis (the Mega Drive in Europe and Japan) in 1989, a full two years before Nintendo had time to respond with the SNES.
This meant that for the first two years of its life the Mega Drive was in direct competition with the NES, a far less powerful console. Sega played on this with its "Genesis Does" campaign, running in magazines and on TV.
The claim was that "Genesis does what Nintendon't" - or, in other words, the sort of stuff the Mega Drive was capable of couldn't be done on the NES. TV ads drove this home with a catchy jingle that hollered: "You can't do this on Nintendo."
