For the past few years I have been using a 2nd generation Apple TV to watch YouTube videos on my LG Smart TV, however as of today Apple have disabled their YouTube app for this particular device.
I presumed I would be able to use a YouTube app on my TV to continue watching videos in this way, after all has anyone ever heard of a Smart TV without a YouTube app? Since most new TVs are smart TVs these days most people I know have one and they all have the capability to play YouTube videos, usually you don't even have to download the app as it is one of the ones that comes pre-installed.
However I cannot find a YouTube app in the LG content store. I've not really tried to install new apps on my TV since getting it so I don't know if I'm looking in the right place, or it is one of those things like with smartphones where there are multiple places you can go and download apps from.
Bizarrely though, despite there being no YouTube app, there is a YouTube kids app, so it's not like LG have never heard of YouTube or anything, they just don't seem to have realised that people other than kids watch videos on it.
