I like to equate the rise of Sweet Cheddars to Breakfast Cereal. My grandmother was born in 1892, and her breakfast choice was oatmeal, although some new-fangled cereals were invented when she was a child. All were healthy and none had added sugar.
Today, cereals have insane levels of sugar and breakfast has become the least healthy meal with little differentiation between products. To break into the cereal market, a company must be a large corporation with deep pockets.
