I've kinda been wanting to know a bit more about the early history of Nick News. I looked at the wikipedia page but couldn't find the info I'm looking for (I also saw that the show was produced by Lucky Duck Productions, saw there's an official website but since business closed there's just a page saying so, with no older pages).
From what I recall, Nick News began airing as a series of specials. I recall one, which I assumed was the first, during the 1992-1993 television season (I remember it having a very brief clip of Kermit the Frog, in news attire; I think that part was also in the commercials). Then I saw another special, titled "We Are the Weird". I most remember it opening with a montage of clips from television shows, such as Family Matters, Dinosaurs (the episode "I Never Ate for My Father" - it was the scene with Robbie talking about his family being carnivores), and The Cosby Show, among others.
I recently found a YouTube video of commercials during Nickelodeon programming in 1991, which included a promo for a special with Nick News host Linda Elerbee titled "The Day the Earth Threw Up", the promo refers to it as a "Nickelodeon Special Edition", and I took from the commercial that she hosted other "Nickelodeon Special Editions" before Nick News started, but I can't find the info I'm looking for (not on the Linda Elerbee page at Wikipedia, not - as I said before - on the Nick News page, nowhere).
