First aired in 1994 as a Beavis and Butt-Head spinoff, Daria was a fantastic animated series about a whip-smart, sardonic, misanthropic highschool girl, her punk friend Jane, and a familiar gang of jocks, dimwits, and cool cats. Daria, the show and the character, was funny, feminist, emo, and awesome. La la la la la. Vice has an oral history of Daria:
Daria was put together by Harvard-educated Lampoon alum Glenn Eichler and Susie Lewis, who spent her days at Temple University doodling MTV logos on notebooks until a classmate suggested she get an internship at the network. His book smarts combined with her street smarts and pop culture knowledge, in a dynamic not dissimilar to that of Daria and her best friend, Jane Lane. They made their project work without a singular creative mastermind like (Beavis and Butt-Head creator Mike) Judge, who wanted nothing to do with the spin-off and was on his way out the door to bigger (and much more lucrative projects) with Fox anyway.
Daria ended up being the longest-running show to come out of MTV's Animation department, surpassing even Beavis and other cultural touchstones like Celebrity Deathmatch...
David Felton, Beavis and Butt-Head writer and creator of the character Daria Morgendorffer): In my script, Daria was ordered to work with Beavis and Butt-Head on a science experiment because their project was a disaster. It seemed like it would be interesting if they had someone to back them up who was a female, but not a sexual object. They certainly didn't think of her in sexual terms—they'd ask her about sexual things, but they called her "Diarrhea" instead of "Daria."
Tracy Grandstaff, voice of Daria Morgendorffer: I was the only female writer on the Beavis staff at the time, so I was the default choice [for Daria]. Janeane Garofalo from the Ben Stiller Show [was a Daria influence] for sure, as well as my own personal inner dialogue from junior high and high school in Kalamazoo, Michigan—and Sara Gilbert from Roseanne, probably more than anyone.
