There are a few things that are unique to each country. They don't get mentioned in more official events, but you notice that they're different if you eer go to other countries. I've focused mainly on TV, but let me know if you can think of other stuff like this and I might add it to the list!
They are:
* The candy/cookie/etc. that's so famous it's doesn't even feel like product placement to mention it on TV. (EXAMPLE: Oreo cookies in the USA, Kexchoklad in Sweden, Pocky in Japan.)
* The entertainer who is super-famous, but pretty much unknown in all other countries. (EXAMPLE: Nordman in Sweden, Heino in Germany)
* The company everybody hates. (EXAMPLE: The public transport company Västtrafik in Sweden; Comcast in the USA)
* The trashiest newspaper that's huge saleswise. (EXAMPLE: Expressen in Sweden; The Daily Mail or The Sun in the UK depending on how broadly you define "newspaper")
* The universally beloved family comic. (EXAMPLE: Bamse in Sweden, Mafalda in Argentina, Calvin and Hobbes in the USA, Tom Poes in the Netherlands)
* That kids' show with a grown man in a fursuit that everybody watched as kids. (EXAMPLE: Barney the Dinosaur in the USA; Björne in Sweden)

Please let me know if any of my examples are incorrect. However, it has to be genuine examples, and not just a sullen Swede insisting that "Nordman is helvetes big in Japan!" And before any Americans start yammering on about Peanuts, I'd like to point out that many Peanuts fans are mainly fans of the animated TV specials who also read the actual comic at some point[footnote]This is not meant to suggest that they're bad; both on the printed paper and on the TV screen, Peanuts is great.[/footnote]. When it comes to Calvin & Hobbes, the only thing people are fans of is the actual comic strip Calvin & Hobbes.
