I don't know if the ban on cigarette advertising applies to cable as well as to broadcast TV. Did GSN ever air shows with cigarette ads left in?
I don't think they left the cigarette ads in, but they definitely aired the Winston IGAS eps and I don't think they left out the mentions of the brand at the top of the show or when Garry would hand out a carton with the winnings.
They also aired the Salem TTTT and Password episodes as well, I think with the references there left intact as well.
I wonder how they went about airing those at the time they did, but didn't ever since then. Special permission from the FCC?
Judging by how long the Winston (Cigarettes) Cup lasted in NASCAR, with the Winston logo very easy to spot during those races up until 2003 (it was RJ Reynolds' decision to cease sponsorship of the races, not any kind of FCC or government law) it sounds like passive "ad placements" where the name & or logo is displayed is still okay, past or present. Same with Gary Moore saying, "Take this carton of Winston Cigarettes with our compliments" is presumed to be allowed, as it is not elaborating on the product which then is not an "ad" per se.
Another example is in older movies & TV shows which were shot on location, there may have been scenes where cigarette signs, billboards, displays, or actual packs were seen. Those scenes are still intact in modern day TV airings as they are not "selling" the product. Even Dick Clark's Blooper Shows would occasionally show brief clips of some of the jingles used in cigarette commercials with no problem, and that was in the 80s.
IIRC in GSN's case, they would voluntarily air Anti-Smoking PSAs as a trade-off. Not sure if and when they stopped that practice.
