1950s: Blackjack and Card Counting

Blackjack became so popular that in the 1950s people began became obsessed with finding ways to beat the system, something that can no longer be done thanks to the rise of online blackjack but still (sometimes) takes place in casinos. It was during the 1950s that the first popular book came out that offered some kind of mathematical reasoning behind blackjack, and also some attempts at bringing skill to the game.

A number of mathematicians brought out books that offered ways that you could beat the system with Blackjack such as counting the cards that were dealt to you and also counting the cards in the pack. This continued into the 1960s and beyond, but the casinos with soon find ways to make sure that Blackjack was fair enough for people to win, but also not vulnerable to people who could count cards.
