Oh, the idea is even older. In 1980, video games downloaded over cable TV, was tested in a few US cities. Intellivision! Same basic idea. Cable service allowed very fast (1 Mbit/s approximately) transmission for the time, so games could transfer in seconds: : https://en.wikipedia.org/wiki/PlayCable

And Sega offered something similar in the USA in the early 1990s too: https://en.wikipedia.org/wiki/Sega_Channel

I think Satellaview in Japan, was the first service of that kind, which was truly successful though.
