As a child in the 70s, I got my information one of three ways. Either watching TV, mostly cartoons, watching the commercials aired between the shows — mostly commercials advertising sugary cereals hawked by cartoon characters, or off the back of the boxes of the aforementioned cereal.
The proper way to eat your breakfast was to glue your eyes to the cereal box as you mechanically shoveled in spoon-full after spoon-full of sweet flakes, puffs, or wafers, reading and re-reading every square inch of the box until you were finished eating.
