I would have guessed it stood for chocolate

Usually when you include the dot it's called TLD or ccTLD (Top Level Domain or Country Code Top Level Domain). Country codes as in ISO 3166 are without the dot, and written with capital letters, and they predate the internet, first published in 1974. The tlds were based on these codes.

There are some minor differences, e.g United States Minor Outlying Islands (UM) and Western Sahara (EH) have a country code, but no tlds were implemented.

Edit: In the article it's correctly written as CH

Sometimes I wonder if Fitbit could have its Swiss website with the domain being fitbit.ch

Helvetica the font is the centerpost of swiss communication and recent graphic design history/culture.

For those wondering, the tld for China is .cn

I knew it was for Switzerland since I see it on their numberplates, but I honestly never questioned what it even stood for. So thanks for that :)

I feel so, so stupid right now.

Ironic that the Helvetii fought the Romans only for their descendants to use a Latin abbreviation as their country code :D
