This is widely regarded as the first electronic television demonstration. Many inventors had built electromechanical television systems before Farnsworth's seminal contribution, but Farnsworth designed and built the world's first working all-electronic television system, employing electronic scanning in both the pickup and display devices.

A number of experimental and broadcast pre World War II television systems were tested. The first ones were mechanical based (mechanical television) and of very low resolution, sometimes with no sound. Later TV systems were electronic (electronic television). For a list of mechanical system tests and development, see mechanical television.
A television set, also called a television receiver, television, TV set, TV, or telly, is a device that combines a tuner, display, and speakers for the purpose of viewing television. Introduced in the late 1920s in mechanical form, television sets became a popular consumer product after World War II in electronic form, using cathode ray tubes .
In 1914 he once again described his system in his presidential address to the Roentgen Ray Society and in 1921 a book was published describing it in some detail. [13] He himself described his system seven years later in the June 1928 issue of Modern Wireless, "Television by Cathode Rays". [14] [15]
