The Game Boy was designed by Gunpei Yokoi and Nintendo's R&D1 team following the popularity of the Nintendo Entertainment System.

The Game Boy has several accessories, including a carrying pouch, printer, camera, and fish detecting radar and more.

Nintendo spent $10 million marketing the Game Boy, highlighting its portability and affordability.

The Game Boy has four operation buttons, a directional pad, and a volume control dial on the right side.

The Game Boy was released alongside six launch titles, including Super Mario Land and Tetris.

Tetris was a critical and commercial success, and its release helped to establish the Game Boy as a major player in the gaming market.

The Game Boy faced competition from Atari's Lynx and Sega's Game Gear, but ultimately outperformed them due to its lower price and longer battery life.

The Game Boy was a huge success, with a lower price and longer battery life compared to other competitors. It sold 64 million units worldwide by 1997 and 119 million units combined with Game Boy Color by 2016.

Nintendo's strong game ecosystem and developer lock-in helped the Game Boy's success, as developers were forced to make games exclusively for the platform.
