Good post and I am coming at this from an American perspective.
I started smoking back in the mid '90's when I was in college and one movie that came out at that time that was big with me and my friends was Pulp Fiction. I loved that movie and still do but they smoke a ton in that film. I don't think that had an influence in me starting to smoke but it definitely glamorized smoking to the point that I wasn't thinking about quitting then.
I do think a lot of older films and TV programs were in some way supported by tobacco companies. There are infamous commercials from the 1960's children's cartoon The Flintstones endorsing Winston cigarettes. There are other examples too of family friendly programming from that time that endorse smoking in some way.
I do feel that there has been a push towards taking smoking out of programs today. Supposedly Netflix is working on taking smoking out of a lot of their future original content. Also, the movie rating system today considers smoking to be a reason to rate a movie PG-13 or R.
Still, I realize smoking was a big part of culture in the past and I don't think it should be cut out if it is meant to depict how things were during a certain time.
Tough issue and I'm not sure what the answer is. I am not pro-censorship but at the same time I hate to see smoking (and, nowadays, vaping) glamorized to a younger generation.
