There are a bunch of free channels on the internet that some TVs can just stream without a dedicated app. These channels are supported by ads like cable/whatever channels, but not locked behind a subscription. VLC is supporting whatever formats they use to allow (or make it easier; IDK) people to watch them if they want.
The other part is that they’re working on web assembly to allow sites to use VLC as their embedded video player.
