ASTRO BOY 1966 Season 1 52 Episodes
]The 1963 black-and-white version of Astro Boy was the first anime to cross the Pacific and penetrate American television. It was highly successful as it drew the highest ratings at that time. It was taken off the air in 1966 as it completed its 104-episode run (193 episodes in Japan), having lost its popularity due to it not being in color and having "depressing" and violent themes and story lines.
