The series is one word - Not two
IMDB has the show incorrectly titled as two words. The title is suppose to be a take on the word Aftermath and is correctly titled as one word, "AfterMASH", not "After MASH".
I kept wondering why this show was never listed on IMDB because I was spelling it correctly in the search and it wasn't showing up. Now I know why when I finally looked up one of the stars of the show instead.
At least Wiki got the title correct.
