Ultraman (ウルトラマン Urutoraman) is a Japanese tokusatsu science fiction television series created by Eiji Tsuburaya. It is a follow-up to Ultra Q, though not technically a sequel or spin-off. Tsuburaya Productions made 39 episodes (40, counting the pre-premiere special) that aired on Tokyo Broadcasting System (TBS) from July 17, 1966 to April 9, 1967.
Its premiere topped the average rating set by Ultra Q and kept climbing each week, marking the show as a success. Although Ultraman is the first series to feature an Ultraman character, it is the second installment in the Ultra Series, after Ultra Q.
This is signified in the show opening by the Ultra Q logo exploding into the Ultraman logo. He and its titular hero became a major pop culture phenomena in Japan, spawning dozens of sequels, spin-offs, rip-offs, imitators, parodies and tributes.
He went on to generate $7.4 billion in merchandising revenue from 1966 to 1987 (equivalent to more than $16 billion adjusted for inflation) and become world’s third top-selling licensed character by the 1980s (largely due to his popularity in Asia).
