Today in the history of the American comic strip: November 27

American cartoonists and writers may not have invented the comic strip, but some argue that the comics, as we know them today, are an American creation. Clearly, the United States has played an outsize role in the development of this underappreciated art form.

11.27.1937: Following the demise of the Betty Boop daily strip in 1935, the Sunday feature disappears as well.

11.27.1950: The first installment of The Jackson Twins appears in print, beginning a 29-year run. Created by Dick Brooks, the comic centered on identical twin teenage girls.

11.27.1977: A Doonesbury Special, an animated film, debuts on NBC. It later won a prize at the Cannes Film Festival.
 

Most of the information listed here from one day to the next comes from two online sites -- Wikipedia, and Don Markstein's Toonopedia -- as well as 100 Years of American Newspaper Comics, edited by Maurice Horn. Note that my focus is on American newspaper comic strips (and the occasional foreign strip that gained popularity in the United States). Thus, comic books and exclusively online comics are not included here.
