#19: Desilu Studios
Desilu Productions, co-founded by Lucille and Desi Arnaz, became a powerhouse in television history. While it started as a vehicle to produce I Love Lucy, the studio expanded to develop groundbreaking shows like Star Trek and The Untouchables.

Desilu’s innovative approach to production, including the three-camera setup and live-audience format, revolutionized the industry. When Lucille took full control of the studio after her divorce from Desi, she became the first woman to head a major television studio.
