My smart TV can connect to anything
If I let it. As it is, I have it connected to a Hotbird dish and nothing else since that provides more than enough TV for me, I probably average less than 1 hour a week looking at the goggle box.
I do get untargetted ads if I watch a youtube vid on my phone but otherwise I have little idea of what's for sale in the world without going to a shop,or looking for a specific item.
