Today in the history of the American comic strip: October 31

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.

 
10.31.1955: Scamp, a comic strip inspired by the 1955 animated movie Lady and the Tramp, debuts. The strip ran for more than 30 years.
 

10.31.2010: Bill Hinds pulls the plug on Cleats, which featured a group of young kids, coaches, and their parents as they dealt with being on, or supporting, a soccer team. The strip ran for nine years.
  
10.31.2010: My Cage is discontinued after three years. Created by Melissa DeJesus and Ed Power, it was considered the first manga-inspired comic strip.

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.
