#accaddeoggi 7 settembre 1927: creato il televisore elettronico

Inizia l’era del piccolo schermo

Il 7 settembre 1927 l’inventore statunitense Philo Farnsworth creò nel suo laboratorio il primo televisore elettronico della storia. A differenza del televisore elettromeccanico realizzato nel 1925 dallo scozzese Baird, il prototipo di Farnsworth trasmetteva le immagini su una superficie sensibile attraverso un tubo a raggi catodici. La competizione tra i due modelli fu vinta in meno di dieci anni dallo statunitense, in quanto già alla fine degli anni Trenta tutti i televisori elettromeccanici furono sostituiti da quello elettronico. Iniziava così l’era della televisione.
