Just look at all the new magazines at a bookstore. There are at least 10 Taylor Swift magazines. Trump has at least two magazines about him. There's plenty of growth in the gun and prepper department. Food magazines are available in quantity.
Magazines are still around, but they're addressed to niches.
I must say I never really understood the economics of newsstand subscriptions. Even when I probably subscribed to 10+ magazines I almost never bought single copies unless I was quoted in one.
Magazines were always mostly relatively niche outside of maybe a few fairly general interest news and personality mags.
