12. The Technology of the 80s Introduced the Game Boy
Nintendo launched Game Boy on April 21, 1989. This hand-held device revolutionized the gaming industry in an instant. Users could play anywhere; that is, if they have a working pair of batteries. The initial 300,000 units sold out for a retail price of $89.99 immediately, and over 118 million were sold throughout the years. That’s a lot of Tetris!
