Possibly even earlier than that. I spent a small part of my misspent youth (~1961) in a TV repair shop. The TVs of that era (in the UK at least) had large rotating turrets to select the channel. We used to burnish the contacts with 'Silvo' and then smear silicone grease over them. That part of the set was then much more reliable than as supplied new. The remainder of course, was not!
