Yes. Pick up a Vogue. A fat magazine with virtually no content but a lot of pictures. A mixture of advertising and photo shoots. There is a whole, massive demographic out there that just loves this stuff, and isn't technical at all.

The existence of vogue shows that there is a demographic who likes to flip through nice pictures. Sometimes they dog-ear the pictures to come back later and look again. People like to leave the magazine lying around their place as a social indicator that they are interested in fashion, and they like to mark which bits of that fashion they're interested in. That's pinterest in a nutshell.

Now go to any magazine rack. There are are broad range of these niches. It's not about replicating a magazine, it's about understanding what purpose that magazine exists for. Is it interesting articles? Wanted ads? Industry information? The purpose and niche of the information is what people want. These all can be more innovatively delivered and shared than a glossy magazine dropped on a doorstep.
