Editing Laugh track (section)

====Hanna-Barbera====
Hanna-Barbera, a pioneering force in American cartoon production, marked a significant departure from its utilization of Douglass's services. The studio embraced the laugh track phenomenon, initially integrating it into their prime-time lineup comprising acclaimed shows such as ''The Flintstones'', ''Top Cat'', and ''The Jetsons''. Subsequently, this practice extended to their daytime programming, notably with the introduction of ''The Banana Splits'' in 1968, drawing inspiration from Filmation's ''The Archies''. Prior to 1971, successful series such as ''Scooby-Doo, Where Are You!'', ''Harlem Globetrotters'', and ''Josie and the Pussycats'' were characterized by the pervasive presence of a comprehensive laugh track.

A pivotal shift occurred at the outset of the 1971–72 season when Hanna-Barbera adopted a nuanced approach by implementing a limited laugh track mechanism employing the MacKenzie [[Repeater (horology)|Repeater]] machine. This device, capable of cyclically playing up to five sound effects, facilitated the repetition of Douglass's distinctive laughs. The auditory composition featured a blend of mild chuckles and hearty belly-laughs, occasionally accentuated by a prominent female laugh, all augmented by a metallic resonance.<ref>{{cite news |title=He Cans Cackles: How Louis G.

The impact of the Hanna-Barbera laugh track extended beyond episodic content to various television specials, notably those featured within ''[[The ABC Saturday Superstar Movie]]'' (ABC, 1972–74), functioning as a platform for the introduction of prospective comedic cartoon series. Occasionally, the studio employed techniques such as deceleration of the laugh track to heighten its comedic effect, as exemplified by the second season of ''The New Scooby-Doo Movies''.<ref name="Iverson"/>

In 1972, Hanna-Barbera continued its experimentation with laugh track dynamics with the production of ''Wait Till Your Father Gets Home''. Notably, this endeavor featured a modified laugh track distinguished by the inclusion of an additional belly laugh, a distinctive departure from their standard practice. Moreover, the laugh track in this instance underwent a deliberate reduction in speed during the production process, marking a singular occurrence within Hanna-Barbera's television repertoire.<ref name="Iverson"/>

The Hanna-Barbera laugh track was discontinued after the 1981–82 television season.

In 1994, laugh track historian and [[re-recording mixer]] Paul Iverson commented on the legacy of the Hanna-Barbera track:
{{blockquote|The Hanna Barbera laugh track did more to give laugh tracks a bad name than Douglass's work could ever have done. Using the same five or so laughs repeatedly for a decade does not go by unnoticed, no matter how young the viewer is.}} Iverson added:
{{blockquote|All it takes is watching an episode of ''Josie and the Pussycats'' alongside of ''Josie and the Pussycats in Outer Space'' and it is painfully obvious. It is a shame that a company as powerful as Hanna-Barbera&nbsp;– who, at its peak, practically owned Saturday mornings&nbsp;– thought so little of their audience by dubbing such an inferior laugh track for so long a period.<ref name="Iverson"/>}}
