When Lucille Ball and Desi Arnaz created I Love Lucy, viewers fell in love with the talented performers. Although network executives were nervous about the show at first, it quickly became a hit. A few years into its run, Ball and Arnaz made another brave move, including Ball’s pregnancy in the show. 

The result of this decision changed the world of TV, and it is often hailed as the first time pregnancy was acknowledged on a major TV show. But it wasn’t the first time Ball was pregnant while taping I Love Lucy.
