"What is the fastest mean of communication?"
"Telephone, Television and Tell a Woman."
With that women found they were needed as telephone operators.
The first woman on USA television was Edna Mae Horner.
When AT&T held its pioneering demonstration of television (click title to entry - thank you) on April 7, 1927, Edna Mae Horner, an operator at the Chesapeake and Potomac Telephone Company, helped guests in Washington, D.C., exchange greetings with the audience in New York. Throughout the presentation, viewers in New York could see and hear Edna as she called eager audience members to the transmitting equipment.
In reporting the day’s events, The New York Times noted that Edna was “one good-looking girl with fluffy hair, and as cool and efficient as if she had been at the television-telephone switchboard all her life.”
