As the use of laugh tracks for Saturday morning series became more common, Douglass eventually added several children's laughs to his library. "Kiddie laughs", as they are known, first saw use for sweetening for the 1973 syndicated television special, "The World of Sid and Marty Krofft at the Hollywood Bowl", but were soon heard on most Saturday morning kids' shows by 1974, such as "Uncle Croc's Block", "Sigmund and the Sea Monsters", "The Pink Panther Show", "The Lost Saucer" and "Far Out Space Nuts".
