Stieg Larsson never mentioned this...

(or maybe he did in the third book, I haven't read it yet):

Every Dec. 24 in Sweden, at 3 p.m., a third to a half of all Swedes sit down to watch the same traditional television program that has marked Christmas for the last 50 years: a lineup of historic Donald Duck cartoons. According to a December report on Slate.com, the show is insinuated in the national psyche because it was the first big holiday program when Swedes began to acquire television sets in 1959. Entire families still watch together, repeating their favorite lines.
