First time I traveled from US to Europe was Spain in 1988, and I was interested to see Burger King and McDonalds there. A decade later, visiting the UK, I was 'surprised' a bit to see so many 'US' brands there. Mid 2000s - visited Shanghai - so many Western/US brands, didn't feel much different than being in NYC. 2010s - visited Russia and Romania - again, many US brands there (or other European/UK brands I knew). I got Sbarro pizza in Moscow - cost about $45 for one large pizza, but still tasted the same.

Lately, I've started noticing 'UK' brand products coming to the US (Persil detergent, for example). Maybe many of these are Unilever brands being exported to more countries?

When people talking about "multinational corporations", this is what they mean. As a US person who's never traveled abroad, it might be jarring (or 'funny') at first to see familiar brands in a 'foreign' country. But we're ... a pretty global society now.
