Animaniacs

Animaniacs is a cartoon series created by Tom Ruegger and executive produced by Steven Spielberg for Warner Bros. Animation that aired from September 1993 to November 1998 and has achieved cult success for many years afterward.

It consists of cartoon segments focusing on various characters in each episode, mainly the adventures of Yakko, Wakko, and Dot; three cartoon siblings who were locked inside the Warner Bros. water tower for six decades in the 1930s. One of its segments, Pinky and the Brain, was successful enough to earn its own spin-off series.

The show's long-lived popularity eventually prompted a revival series taking place in the modern-day, which began streaming on Hulu in November 2020.
