I was ~10 in the mid-80s, remember reading Bloom County every Sunday in the Boston Globe. I didn't get half of what it was about at the time, like why arming a bassalope with a warhead was funny, why Ed Meese didn't want them to say "snugglebunnies!", why Steve sued the camera company when Sean Penn broke his back, or why the gang wanted to visit a "wild, spunky, chunky planet of Mary Lou Retton clones". But things gradually made sense, from reading top looking up things to listening to one of the Big 3 news anchors talk about current events.
Things really started to click when the PMRC hearings staerted up, as I was just beginning to take an interest in music at the time, and the whole Deathtongue --> Billy and the Boingers thing was amazing.
I've always felt that Breathed would come back (and he has come back at times, with "Outland" and "Opus") when he has something fresh to say. Maybe in a world of constant news and constant parody of the news...and a blurry line in between...a 2015 Bloom County won't be quite as subversive or unique as it once was, but I trust that the author wouldn't come back unless he had good material to come back with.
