Robotech: In the mid 1980s, Harmony Gold hired Carl Macek to adapt Japanese animated programming for American broadcast release. Macek originally wanted to adapt The Super Dimension Fortress Macross only, but was instead forced to combine it with two other anime series together, even though they had no relation to Macross. These three series became Robotech. The other two series used are: Super Dimension Cavalry Southern Cross, Genesis Climber MOSPEADA
Harmony Gold's cited reasoning for combining these unrelated series was its decision to market Macross for American weekday syndication television, which required a minimum of 65 episodes at the time (thirteen weeks at five episodes per week). Macross and the two other series each had fewer episodes than required, since they originally aired in Japan as weekly series. The production was successful enough to merit an American produced movie and a spin-off, Robotech II: The Sentinels. Due to unforeseen economic circumstances, cancelled.
