In the year 2003, Professor Tenma is distraught when his son Tobio is killed in a car accident. He loses himself in his latest project, creating Atom, a robot boy programmed to be forever good.

Upset that his Tobio-substitute can never grow up, Tenma sells Atom to Ham Egg, the cruel ringmaster of a robot circus. Atom meets the kindly Professor Ochanomizu, who adopts him, inspires him to become a crusader against evil, and eventually builds him a robot "sister," Uran.

Tetsuwan Atom was the first television anime series to air in a 30-minute programming slot. It was broadcast by Fuji Television and aired on Tuesdays when broadcast began in 1963. The first episode debuted on New Year's Day with a 27.4% viewership rating, with the series later peaking at over 40% rating by the following year. From 1964 onward, the airing was changed to Saturdays.

When American television producer the late Fred Ladd helped NBC Enterprises adapt the series for broadcast in the United States in 1963, the title Astro Boy was used instead of the manga's English title Mighty Atom. The change was forced because of its similarity to the contemporary American superhero character Mighty Mouse, which Osamu Tezuka used as a basis for the character Atom.

Preliminary (7/193 eps)
Created in 1952, Osamu Tezuka revolutionized american cartoons forever when Astro Boy came to our American televisions in 1963. It is recognized as one of the first popular animes to be in America.

Osamu Tezuka offers to younger audiences along with teenagers who have nothing better to do. It's cute brand of comedic satire brought in audiences of both genders. Action and a funny, yet dramatic storyline set in the distant future of 2003 (oh no!) make it so popular to everyone.

This review focuses on the original Japanese version (193 episodes) as released on the Tetsuwan Atom Complete BOX DVD sets and is slightly updated from my previous preliminary review.

Tetsuwan Atom is the first “full-length” (30-minute) weekly TV anime. With an ambitious project devoid of a high production budget, Osamu Tezuka pioneered production methods like limited animation, use of recycled footage, and outsourcing animation work when there was hardly any precedent to learn from. Especially early on, this was in many ways an experiment, and it cannot be viewed under the same critical lens as even subsequent 60s works.

In its most basic premise, Tetsuwan Atom has ...

Preliminary (3/193 eps)
I was around 9 when I first watched the first 10 episodes of Astro Boy on VHS. I had no idea at the moment that it was the 80’s remake of an older show, which in turn was actually a legend in the field as it revolutionized how anime look and feel decades before we had the internet to hype everything with little effort. And here I am some decades later myself, making a small essay on the damn thing. You may have heard from time to time about a series that begat a whole new genre, such as Tetsujin-28 being the first mecha series ...
