In the eyes of most Superman fans, this series consisted of four seasons. Season 1 (1966-1967) was a 30 minute show featuring two Superman segments sandwiched around one Superboy story. Season two made up the first half of The Superman/Aquaman Hour of Adventure (1967) and season 3 filled the last half of The Adventures of Batman (1968). Both seasons 2 and 3 featured the same format of two Superman and one Superboy segments, and consisted of both new material and reruns from previous seasons. Season 4 (1969-1970) saw the series return once more to a stand-alone, 30-minute show; and consisted of only previously aired episodes.
