That was the start of it all.
That was followed by semiconductors, as far as generational changes in tech. Semis were developed largely outside of Japan. The USA is largely the leader in semis, especially Nvidia. But there is no one-country dominance given. the varieties of semi investments. Taiwan Semi is the only real supplier/builder of chips, especially GPUs. Gaming drove the initial wave, and that's been overtaken by AI. Same kind of chip, different business cases.
The USA also leads, arguably, in networking.
