#22: The Show Ended Because Lucy and Desi’s Marriage Was Falling Apart
I Love Lucy did not end because of declining ratings or lack of popularity. In fact, the show was still enormously successful when it wrapped. The real reason was the deterioration of Lucille Ball and Desi Arnaz’s marriage behind the scenes.

Continuing the series became emotionally difficult, even though they tried extending the franchise with The Lucy–Desi Comedy Hour. Eventually, the personal strain outweighed the professional success, and one of television’s most beloved shows came to an end while still on top.
