Short answers, pulled from the story.
Instant History premiered on the 1st of May 1961 on Fuji TV. This date marked the beginning of a groundbreaking black and white anime series that became the second oldest anime television series in existence.
Ryūichi Yokoyama directed the Instant History anime series. He leveraged his existing popularity from the Fuku-chan manga to build a bridge between his comic strip readers and the new television audience.
After its initial run on Fuji TV, Instant History was rebranded as Otogi Manga Calendar and broadcast on the Tokyo Broadcasting System starting on the 25th of June 1962. Parts of the original series also found a home in Knowledgeable University, which aired on the Mainichi Broadcasting System beginning in 1966.
The Instant History series ran until the 4th of July 1964, spanning over three years of broadcast history across multiple networks. This duration allowed the show to reach a wider audience than a single network run could have achieved.
The production team at Fuji TV used research archives from the Mainichi Shinbun newspaper as the primary source material for the historical segments. This archive provided actual photographs and film footage that were mixed with hand-drawn animation to create a documentary-style animation.
