This guy put together a HUGE list of mainly snacks, beverrages and cereals that appeared, were popular or originated during that time.
From the seventies there were those frozen vegetable fries like I Hate Peas, I Hate Spinach which was supposed to get kids to eat veggies if they looked like fries. The funny part of this was that some kids didn't know they were supposed to hate veggies until this product was introduced.
It seems like a good place to find the name of some long forgotten cereal like Quangaroos, an orange-flavored version of Quisp.
Some stuff sounds like it isn too bad it didn't make it and quickly disappeared .. some were ideas before their time ... Skippy Hickory Smoked Peanut Butter ... Malted Milk Lifesavers .... Maple Duds, maple coated Milk Duds ... Pepsi A.M, for your early morning Pepsi fix (more sugar and caffiene perhaps?)
For some ... gone is good ... McDonald's Arch Deluxe ... microwavable pork rinds ... Orbitz ... a soda with suspended colored balls orbiting around in the soda. Nice concept but the taste was awful. I always felt it might have inspired boba drinks ... which do taste good. Just a theory.
Never heard of them, but supposedly there were potato and tortilla chips called "Que Pasa".
Anyway, there's a place to add any foods that might have been missed. There also links for other topics for those time periods. Gnarly, man.
