Also British, and old to boot. I read Tintin extensively as a child and a bit of Asterix. Strangely I never really thought of them as comics before this discussion here, precisely because they were a single long form story per book. I actually remember most Tintins I read being proper hard back affairs loaned from the library.

I read the Beano weekly which is my understanding of what a comic is, lots of two to three page skits as you say.

I never really got into American comics such as Marvel, I guess they fit somewhere in the middle in terms of being a periodical but with a substantial storyline?
