Billiards? Surprised you didn't say Pool. Billiards was a game played by hugely snobby people during the mid to late 19th century until the early 20th century, think Queen Victoria period in the UK. It generally faded out of popularity during the early 20th century and slightly earlier than that in the US and Canada (British Canada only).
As time went on fewer and fewer people played it, even trying to buy or getting a Billiards table became increasingly difficult to buy, due to the lack of interest and the lack of manufacturers. Pool and Snooker overtook Billiards completely.
You might find very old Billiards tables in old gentry homes but they too are rare.
People today rarely know how to play Billiards, even less know the actual rules, the rules perhaps being the only real thing left of the game. Looking forward to playing 0.23 as soon as I have the time.
Merry Christmas, and a peaceful new year to you and your family!
