John Logie Baird invented some of the first experimental television systems. In 1924 he developed a mechanical television system to transmit moving images by means of electrical signals, which he demonstrated on 25 March 1925 at a London department store, Selfridges. It consisted of a spinning disk set with a spiral pattern of 30 lenses.
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.

Family watching TV, 1958. The concept of television is the work of many individuals in the late 19th and early 20th centuries. The first practical transmissions of moving images over a radio system used mechanical rotating perforated disks to scan a scene into a time-varying signal that could be reconstructed at a receiver back into an approximation of the original image.
John Logie Baird transmits a television signal from London to Glasgow by telephone line. September 07: Philo Farnsworth achieves an experimental electronic television image, of a straight line, at his laboratory at 202 Green Street in San Francisco.

John Logie Baird performed the first public demonstration of his "televisor" at the Selfridges department store on London's Oxford Street. The demonstrations of moving silhouette images continued through April. The system consisted of 30 lines and 12.5 pictures per second. [1] June: 13
