I don't think it's becoming more popular, but I really don't know? All I know is that I don't see anyone smoking a pipe when I'm out and about. The humidor is three to four times the size of the pipe area in my local B&M, and all I ever see are cigars being smoked there. The pipe area actually appears to have a thick layer of dust on the majority of pipe related items. The internet is a microcosm to me and can make it appear that it's gaining in popularity. I don't think tobacco use in general is gaining in popularity (actually the opposite), but pipe smoking does seem to be maintaining (fingers crossed)? The internet may be doing more harm than good, as I know that trips to my local B&M and my urge to want to go out and congregate with others has been dramatically reduced since the internet has come around. Although, it has had positive effects as well. I know that I have become accustomed to simply ordering my supplies from the internet and just sitting in my house and enjoying my pipes. This certainly isn't helping grow or add to the popularity of pipe smoking. This is probably just me though. Although, my pipe smoking has not led any of my friends or acquaintances to pick up a pipe; not even those that smoke cigars and/or cigarettes. They just don't want to deal with the whole ritual aspect of it and prefer quick and easy; a real barrier to pipe smoking gaining popularity in my opinion. It's too time consuming for a now, now, now, fast, fast, fast overall pace of life of many people I know.
I obviously have no idea, but would gesture to say 'no' it's not. At least this is my best guess. It's definitely become less popular over time, but I think it's enjoying a slight resurgence for the time being. It's hard to say something is becoming more popular that media, government, and the general majority of the population perceives and dictates as harmful, intrusive, and not allowed in so many places. I'm surprised people are allowed to still smoke, and won't be surprised when the day comes that we'll all be required by law to submit to regular nicotine tests in order to be eligible for insurance coverage that is also required by law. The cute young girl that passes by and remarks that the smell of my pipe reminds her of her grandpa will be obsolete. It will be a cute young girl that passes by and texts the police that someone is smoking a pipe on the sidewalk, followed by an instagram post of my mug with devil horns on a superimposed skull and crossbones. Live it up now, as it's just a high point in an overall steady decline. Again, sorry for the debbie downer perspective. I can't help it. It's just my gut feeling. I hope my gut is wrong as I'd love to see pipe smoking become popular again.
