Considering I'm in the U.S. and I said our...I meant American culture.  

I would agree with this. I never saw Dell comics as a kid either and, in fact, I didn't even know they existed until I joined this forum at the old CBR site. I never saw Gold Keys either and Charltons were available but much rarer than American Marvels and DCs -- which were pretty rare themselves, relatively speaking. I think that was because I was living out in the home counties, rather than in a big city though. I seem to recall having discussed this with tingramretro before and he saw more non-big two published comics than I did back in the day because he grew up in a city or major town.

Super Goof appeared in a number of licensed titles in the UK, none of them by Dell. I think IPC Magazines was one.

Right, and Super Goof's first appearance was in a Dell story. So either Dell stories were being reprinted in the UK by other publishers or, at the very least, those stories were influential upon UK comics. Thus, while you may never have seen a Dell comic in the UK, Dell still had an important influence upon the comics of the UK.

I knew of this many years ago when watching a documentary on World War II and he was on the hit list of execution if Germany had conquered Britain.  Many others too (Comics Books that kept the spirits up; etc) were listed too and I don't know who because the documentary was focusing on Dudley D. Watkins. 

Tin, is right on the nose!

I agree Dell & Archie were very important. I wonder if more people have read these two publishers more than any other publishers over the years.

From my perspective here knee deep in Golden Age comics, the answer is unquestionably Dell. Not only did that publisher produce more individual comics than any of its contemporaries, it was responsible for many of the era's bestselling titles including the blockbuster Walt Disney's Comics and Stories. Dell had the best selling funny animal titles (Looney Tunes and Merrie Melodies, Walter Lantz's New Funnies, Our Gang Comics featuring Tom & Jerry) and the best selling Westerns (Gene Autry, Roy Rogers, Red Ryder, The Lone Ranger), held the licenses for big-name characters like Tarzan, Dick Tracy, Zorro, and Raggedy Ann, and was the home of such mega-stars of the medium as Walt (Pogo Possum) Kelly, Carl (Donald Duck) Barks, and John (Little Lulu) Stanley. It was one of the few publishers that produced comics aimed at beginning readers and preschoolers. Dell accepted no outside advertising, consistently providing cover-to-cover content, and was comparatively immune to the rancorous vilification of the industry that grew steadily throughout the '40s and early '50s. That they aren't more widely recognized as a major player in the medium is due largely to the myopia of comics historians unable or unwilling to see anything not related to super-heroes as important or worthwhile.

Cei-U!
Here endeth the sermon!
