Growing up in the 70s and 80s, the only pasta shapes I knew were spaghetti, macaroni, lasagna, and PERHAPS linguini or fetuccini. Nowadays even a Walmart on the Great Plains will stock fusilli, farfalle, rigatoni, penne and perhaps even gnocchi. So I'm wondering when the Great Pasta Invasion occurred. The early 90s?
PS--As ever, I'm sure this trend began much earlier in the urban corridor of the northeastern US.
