When I've had to bust out microfilm to look up information from the 1960s and 70s at my shop, my 20-something coworkers act like I'm unrolling the Dead Sea Scrolls.
What really gets them in those old editions of the Podunk Press are the huge "ROP" grocery store ads (with great clip art food) and the 10-page clashified section. There literally has not been a point in their conscious lifetimes that those things were not available online.
In a related item, the plot line of Yacht Rock clashic "Escape (The Pina Colada Song)" is totally lost on those 20-somethings.
I worked at a couple of newspapers that were never of any quality. I mean, 100 years of shoddily sourced news and press releases with grip and grins (and a good indicator of how my journalism career panned out) But whenever I flipped through to the clashifieds, it became clear how valuable that 25 cent investment really was. Dozens of pages of things there was no other way of ever knowing about otherwise.
