DuckTales
The cartoon premiered worldwide between 18–20 September 1987 (the time and date varying between markets), with a television movie special entitled ""The Treasure of the Golden Suns"", which was later split up into a five-part serial in future reruns. The first season, aired between 1987–88, consisted of 65 episodes, the "magic number" requirement needed for a show to have a weekday syndication (five days a week for thirteen weeks). Disney then commissioned three more seasons – the second season (aired between 1988–89) consisted of two television specials entitled "Time Is Money" and "Super DuckTales", with future reruns splitting them into two five-part serials; the third season (aired between 1989–90) consisted of 18 episodes, with it forming an hour-long syndicated block alongside ""; and the fourth season (aired during late 1990) consisted of seven episodes (including three unaired episode meant for the previous season), which was used to form a two-hour long syndicated block called "The Disney Afternoon", consisting of "DuckTales" and three other half-hour cartoons.
Chip 'n Dale: Rescue Rangers
Except for the five-part set of episodes made from the pilot movie, each 22-minute episode of the series was self-contained. Plot points introduced in each episode stayed in the episode and any character development did not appear to continue through to future episodes. Most of the episodes followed a similar format, where in the next case was presented at the start of the episode, then the bulk of the episode had the sleuths gathering clues and investigating the situation. In the last few minutes of the episode, the case was resolved, usually in dramatic fashion and the final moments would have a humorous wrap up scene between the Rangers."Rescue Rangers" was originally conceived as the first of three new companion shows to Disney's popular "DuckTales" series, which had more than doubled the ratings among child audiences in its time slots after its debut in the fall of 1987. Disney had originally invested $20,000,000 in "DuckTales" and then invested $28,000,000 in "Chip 'n' Dale's Rescue Rangers".
