Oh, very interesting. The Game Boy and Game Boy color sold 118.69 million units worldwide in its lifetime. Wow, that’s almost as large of a market as modern-day smartphones.
Of course, now that I think about it in hindsight… yeah, our family definitely bought two, not one, Game Boy Colors well before we started buying our first cellphones. Before that, we bought two “toy” cell phones, which were shaped like a real cellphone model, but the fancy telecommunications circuitry was replaced by a tiny, cheap embedded system that did nothing but play pre-recorded PCM waveform sound sequences when different buttons were pushed. In some sense, pretty sophisticated for a toy as the sound quality was quite good, but the embedded electronics circuitry was not quite good enough to be a real cellphone.
