In
1928 Philo Farnsworth made the first public demonstration of a purely
electronic television. During the 1930s several countries began broadcasting,
and after World War II it spread to millions of receivers, eventually
worldwide. Ever since then, electronics have been fully present in television
devices.
Modern
televisions and video displays have evolved from bulky electron tube technology
to use more compact devices, such as plasma and LCD displays. The trend is for
even lower power devices such as the organic light-emitting diode displays, and
it is most likely to replace the LCD and plasma technologies.
