Fun read about web browsers on consoles
Found this article today: https://24ways.org/2012/unwrapping-the-wii-u-browser/
It's specifically about the Wii U browser, and it's from 2012, but it's fun to see how people were thinking and talking about non-phone, non-PC web platforms back then, and also how much Nintendo/Sony discouraged this kind of development and use-case through their decisions to make their web browsers harder to access.
On a technical level, the Switch and PS5 browsers are much more advanced than Wii U and PS4 counterparts. They are also kept up to date and can handle larger and more modern pages. Microsoft/Valve also have modern browsers on their consoles, but these are more readily accessible and embraced as features.
Also here's the link to the Iwata Asks interview mentioned in the article: https://iwataasks.nintendo.com/interviews/wiiu/internet-browser/0/0/
