What arcade game was the first to save a high score?

Video games were always about getting the highest score, even from the early days of Pong.

But, while it’s hard to believe, there actually was a time when your highest scores were only recorded in your head (or on film if you thought to bring a camera along and were willing to pay some random dude at the mall to develop it for you).

Video game history changed forever when this game was released, and for the first time players could save their scores to the arcade machine — creating a new caste of unlikely legends.

Which game made this bold choice and altered the future of video games?
