As a kid from France , the publishing company " Larousse" introduced in the early 70's the History of France in a comic format , each book  representing a moment in time was drawn and written by different artists with no restrictions , meaning some artist depict mild nudity or added blood beside somebody who got assassinated for impact . So by 8 years old i had a very good idea what happened in France between the Roman Empire and 1977 .The CBC's own version of history labelled as " pop history for kids " would be an insult at the kids intelligence , Don't forget at the time kids in Europe were introduced to Japanese manga " Goldorak" Albator " which were at the time considered violent but with mature ideas , also at 7.55 pm an animated show called " l'histoire de l'homme " was playing too , i would suggest you check it out  and ironically speaking   it aparently got broadcasted in Canada by the CBC ...
