Have a good hard look at the April 2009 issue of Blender magazine featuring Kelly Clarkson on the cover because it’s the last one you’ll see — ever. According to Fortune, Blender has folded and its editor in chief, Joe Levy will be moving to Maxim magazine.

Ad pages at Blender also plunged 31% last year and another 57% from January through April, according to the Publishers Information Bureau and Media Industry Newsletter. Monthlies as a whole, by comparison, sank 12% last year and another 22% through April. Ad pages at Maxim fell 11% in 2008 and 37% from January through April.

It seems Blender had it tougher than most magazines in terms of ad sales last year. Yikes.
