My folks pulled aside the January/February issue of the AARP magazine that had a short article about Jonathan Gruber's and Nathan Schreiber's new graphic novel Health Care Reform: What It Is, Why It's Necessary, How It Works. It's a short piece, barely a couple inches of column space. But it does include a short quote from Gruber: "I didn't think of a graphic novel as sort of a serious medium."
I don't know Gruber's age or anything, but that the article appears in an AARP publication is interesting in that it's directed towards an older audience who's conception of comic books is rooted in a decidedly pre-Watchmen, pre-Maus era. In other words, they're more likely to have an idea of comics that is based more in the 1950s and '60s in which comics were decidedly material for children.
I don't know who's writing for the AARP but I think it's great that they're willing to cover topics that could potentially challenge really long-held beliefs.
