A franchise founded in fishnet

The Sports Illustrated Swimsuit Issue - An intellectual history. I enjoyed how he specifically mentions a 1978 Cheryl Tiegs photo as "a watershed moment for cheesecake". Since I was 15 at the time, I remember that photo very well. (He says it was a "white fishnet top", but most males my age could tell you that it was a one-piece suit). As for it being a "watershed moment", let's just say there's an easy joke there that I'm feeling too polite to tell.
