#15: First Pregnancy on TV
When Lucille became pregnant during the second season of I Love Lucy, network executives hesitated to address it on-screen. She and Desi pushed back, resulting in a groundbreaking storyline where Lucy Ricardo becomes pregnant.

The episode featuring the birth of Little Ricky aired the same day Lucille gave birth to Desi Arnaz Jr., drawing over 44 million viewers—a record-breaking audience. By addressing pregnancy on television, she challenged societal taboos and normalized a natural part of life.
