This ran from 1926-2005, though the title changed a few times, I guess. It was the first magazine devoted exclusively to science fiction, and over the decades it had a huge influence on the genre. Alas, it now exists only as an online magazine (in which I have no interest). I'm afraid I've never been really familiar with the magazine, but I do have an issue from June 1976 (at which point it was called "Amazing Science Fiction"). It's one of a few magazines I'd bought from a kid on the school bus, in the late 80s (see Isaac Asimov's Science Fiction Magazine). I probably read it around the time that I bought it, but now I don't remember anything about it. But I also have an issue from summer 2000 (under the original title). Unlike the older magazines, which were in digest format, this was a full-sized magazine. (I have no idea when the format changed. And at various points, the magazine's publication became somewhat erratic, I guess. You should read Wikipedia to learn more about all that, if you're interested.) Anyway, I basically got this issue because it contains a story by J. Michael Straczynski, set in the Babylon 5 universe. And I guess I don't know what else to say, except that I feel sort of ashamed that I don't know what else to say. Because, seriously, this magazine is just so iconic, I almost don't have the right to even call myself a science fiction fan, because I'm not familiar enough with the magazine.
