Was the NES the closest thing to a monopoly as a system can get?

Gameboy comes to mind had like zero competition.

Well there was the Atari Lynx when it came out. Plus the Sega Gamegear later on.

And the closest thing i can think of in terms of monopoly would in terms of electronics would be a Windows or iPod. Nothing came close in console gaming that's for sure. Although idk what the Atari 2600's market share was.
