The Big Stuf didn't hit the spot, and it was discontinued after about seven years on the market. It's not 100% clear why the giant cookie didn't last longer, but Fast Company's Sandie Glass surmises it might have been too big for kids' appetites.
The first iteration of the Juliettes lasted from 1984 to 1985, but they were not long for this world. They made a shocking comeback in 1993 as a completely reimagined cookie and this version of the Juliettes lasted slightly longer, until 1996.
