I would argue it is closer to 60 years.

One of my favorite fun facts about video game consoles is that both the PlayStation and CD-i exist largely due to Nintendo being an ass to Sony and Phillips while looking for a CD-ROM add-on for the SNES to compete with the Sega CD. After getting the run around, both companies basically said ‘fine fuck it we are making our own consoles with blackjack and hookers…’

People aren’t okay with mediocrity. Monopolistic practices make it hard to have other choices.
