there are and will continue to be many more star trek faces, but i bet lucy's face is far more recognizable globally than any star trek character's. i'm not trying to disrespect star trek, i'm just saying there's something about lucille ball that people love. she's like everywoman.

She did indeed commission Star Trek along with Mission: Impossible and Mannix, all within a couple of years. In fact, as Desilu produced far more forgettable and quickly-cancelled shows under Arnaz, Ball
had to cut back losses and expenses greatly (Desilu had been struggling financially until her takeover) and only commissioned things which she was reasonably confident would be a success.
