I call them TV sets too. Sounds funny.
I also say Television Set... I once read or heard something where someone was making the point that the proper term is not “The Tellie” or “Tee-Vee”, but Television Set. I also don’t own one.
Never thought about that. I have been calling them "TV sets" since the '50s when I used to go to the store with my Dad as he tested the tubes to check for bad ones. I guess that it is similar to my Dad calling our fridge an "ice box."
