Question: In what year was the comic book publishing company, that Simpsons Illustrated led to the establishment of, founded?
Context: The following is a list of comic book series based on the animated TV show The Simpsons and published by Bongo Comics in the United States.  The first comic strips based on "The Simpsons" appeared in 1991 in the magazine "Simpsons Illustrated" (not to be confused with the comic publications from 2012 bearing the same name), which was a companion magazine to the show.  The comic strips were popular and a one-shot comic book entitled "Simpsons Comics and Stories", containing three different stories, was released in 1993 for the fans.  The book was a success and due to this, the creator of "The Simpsons", Matt Groening, and his companions Bill Morrison, Mike Rote, Steve Vance and Cindy Vance created the publishing company Bongo Comics.  By the end of 1993, Bongo was publishing four titles: "Simpsons Comics", "Bartman", "Radioactive Man" and "Itchy & Scratchy Comics".  Since then, many more titles have been published, out of which "Simpsons Comics", "Bart Simpson", "Bart Simpson's Treehouse of Horror", "Simpsons Super Spectacular", Simpsons Summer Shindig, and "Simpsons Winter Wingding". Bongo Comics Group is a comic book publishing company founded in 1993 by Matt Groening along with Steve & Cindy Vance and Bill Morrison.  It publishes comics related to the animated television series "The Simpsons" and "Futurama", as well as the "SpongeBob SquarePants" comic; along with original material.  It was named after Bongo, a rabbit character in Groening's comic strip "Life in Hell". Heinemann Library is an imprint of American book publishing company Capstone Publishers.  It used to be a part of the educational publishing branch of the British book publishing company Heinemann. "The Book Job" is the sixth episode of the twenty-third season of the American animated sitcom "The Simpsons".  It originally aired on the Fox network in the United States on November 20, 2011.  In the episode, Lisa is shocked to discover that all popular young-adult novels are not each written by a single author with any inspiration, but are conceived by book publishing executives through use of market research and ghostwriters to make money.  When Homer hears this, he decides to get rich by starting work on a fantasy novel about trolls together with Bart, Principal Skinner, Patty, Moe, Professor Frink, and author Neil Gaiman.  Lisa, who does not think writing should be about money, decides to write a novel on her own.  However, she is constantly distracted by other things and fails to make any progress on it.  After selling their novel to a book publishing executive, the group members later discover that the executive has replaced the trolls with vampires because vampires are more popular.  In an attempt to replace this new version with the old before the novel goes into print, they break into the book publishing company's headquarters. This list of comics publishing companies lists companies, specifically publishing companies who primarily publish comics.  Comic art is an art medium used to present ideas or stories via images.  The images are usually arranged in panels in sequence that convey the story.  Sounds are expressed using speech balloons and onomatopoeia.  European comics have existed since 1837, when Swiss artist Rodolphe Töpffer published "Histoire de M. Vieux Bois".  The oldest comic publishing company on this list is the now-defunct book publishing company, David McKay Publications that was founded in 1882 and published comics from 1935 to 1950.  Most comic publishing companies were established in the United States of America where comics became popular in the mid 1900s. Simpsons Illustrated was a companion magazine to the American animated television show "The Simpsons".

"Simpsons Illustrated" was published between 1991 and 1993 and led to the establishment of the Bongo Comics Group. Disney Comics was a comic book publishing company operated by The Walt Disney Company which ran from 1990 to 1993.  It was connected with W. D. Publications, Inc., which was a subsidiary of The Walt Disney Company that published "Disney Comics" during that time span.  W. D. Publications, Inc. created Disney Comics in 1990 so that The Walt Disney Company would not have to rely on outside publishers such as Gladstone Publishing.  In the USA, Disney only licensed their comic books to other publishers prior to 1990.  Since the demise of the Disney Comics line, Disney has licensed out their properties to various US comics publishers, while continuing to publish comics in the since-defunct magazines "Disney Adventures" and "Disney Adventures Comic Zone", as well as numerous book projects, and has reentered the periodical comics market through their 2009 purchase of Marvel Entertainment.
