All fiction novels, Science and Fantasy, Detective or Adventure any thing except romance. For decades it was paper backs, since the mid 90’s, Digital downloads first on a kindle now on my IPhone. I’ve several hundred purchased thru Amazon on the phone. Had a subscription to “Scribe” for a few years, now it’s Amazon Unlimited or the “Libby App” for the local library.
Like several users mentioned, I too subscribe to a wide variety of magazines over the decades past, Guns, Handloading, American Rifleman, North American Hunter, Sports, Woodworking, Motorcycles to name a few interests, but…… no more magazines, except the NRA AR, these days it’s YouTube or digital books on the cell phone.
