The Disney Afternoon

The Disney Afternoon (later known internally as the Disney-Kellogg Alliance when unbranded) was a created-for-syndication two-hour animated television block programming produced by Walt Disney Television Animation and distributed through its syndication affiliate Buena Vista Television. Each show from the block has aired reruns on Disney Channel and Toon Disney. Disney Channel reaired four shows (Darkwing Duck, TaleSpin, DuckTales, and ) on "Block Party," a two-hour block that aired on weekdays in the late afternoon/early evening. 
The Disney Afternoon's block had four half-hour segments, each of which contained an animated series. As each season ended, the previous series would shift while the remaining three would move up a time slot, as new show would be added to the end. The Disney Afternoon itself featured unique animated segments consisting of its opening and "wrappers" around the cartoon shows.
The Disney Afternoon originally ran from September 10, 1990, to August 29, 1997. For the 1997 and 1998 television seasons, it lost its name but was known internally as Disney-Kellogg Alliance, shortened to 90 minutes, followed by its gradual replacement by Disney's One Too for UPN in 1999. Some of the shows also aired on Saturday mornings on ABC or CBS concurrently with their original syndicated runs on The Disney Afternoon. 
"Goof Troop" is the only show to reach the 2000s, with the 2000 direct-to-video finale "An Extremely Goofy Movie". The only shows to get as far as the 2010s and 2020s are "DuckTales" as a reboot and "Darkwing Duck" as a show within the reboot on Disney Channel (& Disney XD), a reboot on Disney+, and "" with an upcoming live-action animation hybrid film on Disney+.
Background.
The Disney Afternoon goes back to Michael Eisner becoming Disney's CEO in 1984 and his push into steady animated television production, which would be based on new characters to bring in new young fans, with a newly launched TV animation department. He set up a Sunday meeting at his house days consisting of creatives. They included Tad Stones from feature animation and Jymn Magon and Gary Kriesel from the music division. "Mickey and the Space Pirates" was pitched by Stones, but was turned down being that Mickey Mouse is the company symbol, thus wanting to do him right. Stones also pitched a "Rescuers" TV series – the sequel was already under development at the time. Eisner suggested the Gummy bear as a series, given his kids liked the candy. Disney Television Animation's first two shows, "The Wuzzles" and "Adventures of the Gummi Bears", were sold to two networks, CBS and NBC, respectively, for their Saturday morning cartoon blocks.
History.
In the fall of 1989, "DuckTales" and "" were being offered in syndication as an hour long weekday afternoon block. The new block kept these shows, and added "Gummi Bears" and "TaleSpin". "The Disney Afternoon" programming block, as a named block, premiered on September 10, 1990 via Disney's syndication arm Buena Vista Television.
However, around the same time, Disney had purchased Los Angeles TV station KHJ-TV, channel 9, from RKO General, and renamed it KCAL-TV. At the time, Disney's syndicated cartoons had been airing on KTTV channel 11, and many of the other Fox O&Os and affiliates also aired the block; this may have been due to the fact that the Walt Disney Company's chief operating officer at the time, Michael Eisner, and his then-Fox counterpart, Barry Diller, had worked together at ABC and at Paramount Pictures. Disney opted to move the block onto their newly purchased station; furious at the breach of contract, Diller pulled "DuckTales" from all of Fox's other owned-and-operated stations in the fall of 1989. Diller also encouraged the network's affiliates to do the same, though most did not initially. This caused the retaliatory formation of Fox Kids. (Ironically, most of the assets of Fox Kids would be bought by Disney in 2001 via their acquisition of Fox Family Worldwide.)
As the years went on, new shows would be added at the end of the block, with the oldest shows being dropped from the lineup. The 1991-92 season, for instance, saw "Gummi Bears"' removal, and "Darkwing Duck" being added to the end.
By the fifth season in 1994, the block had undergone a makeover, with the primary branding being the block's initials, "TDA". At this point, the original idea of shows being added and removed yearly was dropped, as both new and old shows were now stripped all week, or only aired on certain days. The original four shows were gone from the line up by the 1995-1996 season. The lineup at this point included "Aladdin" and "Quack Pack" stripped, while one daily slot was split between "The Shnookums and Meat Funny Cartoon Show" and "Gargoyles", book-ending three days a week of "Bonkers".
The Disney Channel had developed its own copy, called "Block Party", concurrent with TDA's sixth season, that was similarly scheduled and stripped with early "Disney Afternoon" series like "TaleSpin" and "Rescue Rangers".
Disney-Kellogg's Alliance.
By August 1996, owing to decreasing business in the syndicated children's television market due to new competitors such as the cable networks Cartoon Network and Nickelodeon, and the new networks The WB and UPN with having children's blocks of their own, Buena Vista agreed with the Leo Burnett agency to market and distribute a revamped version of the block for the 1997–98 and 1998–99 television seasons. Buena Vista established a partnership with Leo Burnett and Kellogg's—who had been a major sponsor of The Disney Afternoon, to purchase an amount of dedicated advertising inventory. The new block did not carry any blanket branding, but was referred to internally as the "Disney-Kellogg Alliance."
With the September 1, 1997 season started, the block dropped "The Disney Afternoon" name, a half-hour from the stripped block and the "Gargoyles" series. Moving to the Disney Channel were "Disney's Aladdin" and The Lion King's "Timon & Pumbaa". "", which was shared with ABC's "Disney's One Saturday Morning" (which broadcast their own set of episodes), premiered on the block. "Mighty Ducks" and "Quack Pack" reruns shared the second slot in a Monday, Tuesday, and Wednesdays through Fridays, split respectively. "DuckTales" repeats filled the third half-hour slot, with flexibility for the local station to air it at other times.
In 1998, Disney reached a deal to program a new children's block for UPN, "Disney's One Too", as a replacement for that network's internal UPN Kids block. The syndicated block ran until the debut of "One Too" on September 6, 1999.
International broadcasts.
Some of The Disney Afternoon's shows also aired on international versions of Disney Channel (including Disney Channel Southeast Asia), Toon Disney (later Disney XD), Disney Junior (including Disney Junior in Southeast Asia) and Disney Cinemagic, and on several local channels in various countries. In Europe, blocks similar to "The Disney Afternoon" were produced, mostly with names which translate in English as "Walt Disney Presents" (not related to the anthology series). Furthermore, shows that never aired on the American version of "The Disney Afternoon" (such as "The Little Mermaid" and "The New Adventures of Winnie the Pooh") did air on foreign versions of the block.
In Edmonton, Alberta, Canada, the city's then-independent TV station ITV (now Global Edmonton) produced its own version of "The Disney Afternoon" over roughly the same period as the American block, but only once per week in a two-hour block on Saturday afternoons, though using the same cartoon lineup as the American weekday block. Apart from the animated introduction, the block did not use any Disney-produced wrapper segments, instead of using locally produced live-action segments between programs with host Mike Sobel. ITV (and thus the Sobel-hosted version of the block) was at that time also available on cable and satellite in various mid-sized and smaller markets across Canada, as far away as St. John's.
Disney Parks.
Characters from the shows first appeared in Disney Parks with the debut of Mickey’s Birthdayland in the Magic Kingdom, Walt Disney World.
The popularity of The Disney Afternoon led to a temporary attraction at Disneyland in Fantasyland called "Disney Afternoon Avenue." Disney Afternoon Avenue was a feature of Disneyland from March 15 to November 10, 1991, two years before Mickey's Toontown (a name linked to the film "Who Framed Roger Rabbit") opened in January 1993.
On September 14, 1991, then-Disney owned KCAL-TV broadcast a one-hour TV special "Disney Afternoon Live!", which included the opening of Splash Mountain, at Disneyland.
