Also simply called the "Transition", this is the time period between the 80s and 90s, from 1989 to 1991, possibly very early 1992. This corresponds with the administration of George Bush. The Cold War was over, but the 90s had not started yet since Bill Clinton was not yet in office. Cartoons of the time period were Teenage Mutant Ninja Turtles (along with their live-action movies) at the height of their popularity, the Nicktoons like Dough, Ren and Stimpy,and Rugrats, Captain Planet, and the latest Super Mario brothers cartoons to name a few. USA's cartoon express was still stubbornly hanging on though. This was also when music made a change from the 80s "hair bands" to the Seattle Sound and the grunge scene. Hip hop and rap were becoming more mainstream. The fashion was somewhat of a hybrid with 80s and 90s, neon colors remaining popular. This is also the same time that The Simpsonsfull length episodes premiered on the young FOX Network.
The Transition Era was awkward for all involved due to the drastic changes that occured. This has not occured before and so far not since.
