The third largest-selling brand of coffee in the US, Eight-O-Clock Coffee started out as A&P Food Store's house brand of light-roasted "breakfast" coffee in 1919, and was sold in A&P stores alongside their other original roasted blends "Red Circle" and "Bokar."
Over the years, the "Eight O'Clock" brand came to encompass the rest of the A&P coffee lineup as a brand name as well as a type of roast. In the early 1980's, A&P began licensing the coffee to be sold in other supermarkets - including their competitors. Eight O'Clock has been owned by India's Tata Group since 2005.
I find it interesting that in recent years, almost every supermarket has added a custom grinder to their coffee aisle. When I was a kid, A&P was the only store where you could get coffee ground to order - and every checkout aisle had a coffee grinder built in right by the cashier's station so the coffee could be freshly ground just before you left the store. I wonder what happened to all those huge red grinders? They were big, heavy, bullet-proof, and built to last a hundred years by the Hobart Company. I'd love to have one in my kitchen, wouldn't you?
