Anyway, among the many other characters created in the Archie universe, the ones of which you may have heard are Josie and the Pussycats (mystery-solving rock band) and Sabrina the Teenage Witch. And this is entirely because of their appearances in other media.
So let's talk about Sabrina. And to clear up any confusion before we start, I do not mean the British model Sabrina, the frequent Goon Show punchline, although she did appear in Blue Murder at St Trinians so has a comics connection.
Although either one of them may have influenced the episode of Sabrina The Teenage Witch where Melissa Joan Hart magically got huge boobs she couldn't get rid of.
So Sabrina first appeared in Archie's Madhouse issue no 22 in 1962 as a back-up strip by writer George Gladir and artist Dan DeCarlo. She is introduced as an almost malevolent character and we are shown the "rules" of witchcraft in the Archieverse. For example, witches don't sink in water.
Also worth noting (if you're me) is that there was a cartoon series that ran from 1971-74, itself a spinoff from The Archie Comedy Hour, which was a show that also gave us The Groovie Goolies.
Archie has been making huge advances in its storytelling in the past ten years or so. Previously being a regarded as horribly stuck in its past having refused to move with the times it seemed to exist in a perennial 1940s, a world where the civil rights movement never happened, women were second class and homosexuals did not exist, now it gave us lots of interesting new spins on the traditional Archie stories.
We were given Kevin Keller, Riverdale's first gayer, who was seen eventually marrying his soldier boyfriend.
Roberto Aguirre-Sacasa and the artist was Francesco Francavilla and the writer was teamed up with Robert Hack for the new on-going Sabrina series.
Well, I don't want to spoil it. It's a masterpiece of horror comics art. Sabrina #1 is available right now and I highly recommend it.
