The '80s saw an increase in electronics toys, and by decade's end we had peaked ...
No. 1: Nintendo Gameboy
Thank God for beginning and end dates. That allows us to include Nintendo's Gameboy on this list. It was introduced in the last half of 1989, but kept chugging along in popularity well into the '90s.
Until the Gameboy came out, most handheld games played just a single game -- table tennis, baseball, football, you name it. Gameboy wasn't the first handheld device with games you could swap out, but it did popularize the cartridge format in a handheld device. It had a black and white screen, but that was still high tech for the times.
The thing was awesome. And helping add to its popularity was a surprisingly simple -- albeit addicting -- game by the name of Tetris. Tetris did more to accelerate the device's popularity than the sheer coolness of it, itself.
That's it for our list of the top toys of the '80s. Now head on up to your attic or down to the basement and see how many of these relics you have laying around.
