The 1920's was a decade of profound social changes. The most obvious signs of change were the rise of a consumer-oriented economy and of mass entertainment, which helped to bring about a "revolution in morals and manners." Sexual mores, gender roles, hair styles, and dress all changed profoundly during the 1920s, and this revolution was impacted even more rapidly after the invention of television in 1927.
1927 TV was invented: Electronic television was first successfully demonstrated in San Francisco on Sept. 7, 1927. The system was designed by Philo Taylor Farnsworth, who had been working on it since 1920. Electronic television is a type of television that uses electronic signals to produce images on a video screen. Philo Farnsworth (August 19, 1906 – March 11, 1971) was an American inventor best known for his 1927 invention of the first fully functional all-electronic television system. Holding over 300 U.S. and foreign patents during his lifetime, Farnsworth also contributed to significant developments in nuclear fusion , radar , night vision devices, the electron microscope , baby incubators, and the infrared telescope .
