NBC ran two new segments of Birdman each Saturday, separated by a segment of The Galaxy Trio. The character of Birdman was revived three decades later in the Cartoon Network/Adult Swim TV series Harvey Birdman, Attorney at Law, and several characters from Birdman and the Galaxy Trio appeared in this revival.
