Coming from an American perspective... Remi stopped writing The Adventures of Tin Tin the year I was born (1976), so I never really knew much about it... before this box office film, I'm not personally even aware of how or where it would be known to American youngsters. On the other hand, I'm no longer young myself, I don't know what kids know about these days. But my point is, I don't see Tin Tin as being well-known to children in the US. So I can see the Hobbit trailer as perhaps being a good way to bring young people in to see it who wouldn't otherwise know about it.
I remember seeing the Tin Tin trade paperbacks (what would today be called "graphic novels") in American bookstore chains like B. Dalton's and Brentano's in the late 1960s and early 1970s. I didn't have the money to buy them as a kid, but enjoyed reading through them while hanging out in the bookstores. I enjoyed the art and the stories, and the combination of action and humor in exotic locales which I also enjoyed in the "Jonny Quest" TV series at that time.
You can find those collections in the manga/comics/graphic novel sections of a lot of American libraries, so many kids (and older adult comics enthusiasts, who are probably the target audience for these kind of things) are familiar with them. I saw a store devoted solely to Tin Tin merchandise in San Francisco a few years back.
