Here's what passes for good news in the world of print science-fiction magazines: the "big three" magazines only saw circulation declines in the low single digits in 2008, compared with double-digit declines in recent years.
Warren Ellis searched through the new edition of Gardner Dozois' latest Year's Best Science Fiction volume, and found the latest ill tidings for the big science fiction print mags. Analog Science Fiction And Fact lost 1,400 readers, or about 5.1 percent, falling to just under 26,000 copies of each issue in circulation. Asimov's Science Fiction and The Magazine Of Fantasy & Science Fiction both saw drops of 2.7 percent each, to around 17,000 copies and 16,044 copies respectively.
These are actually fairly gentle declines, compared to previous years. According to Ellis, Asimov's lost 5.2 percent of its circulation in 2007, 13.6 percent in 2006 and 23 percent in 2005. The last time we reported on circulation numbers, F&SF had seen an 11.2 percent drop, to around 16,489. (That was only six months ago though.)
