/vt/ - Virtual Youtubers

setting a predetermined time frame to decide "retro-ness" doesn't really work because people wouldn't consider something retro until it's no longer being widely represented by the contemporary.

crt TVs have been pretty much replaced by LCD TVs but not everyone will call them retro just yet (to the layman, they look the same, they have a screen, some buttons, speakers, they're just thinner).
but if it had knobs and 2 metal rods sticking up from them, yep that's retro.

the modern bicycle frame was invented more than a hundred years ago but people wouldn't call a 50 year old bicycle retro because it still looks the same (as in the shape, more or less) as the bicycles they see every day.
but show them a penny farthing, yep that's retro.
