Since the first projection
televisions, comprising only volume control and channel selectors,
nowadays, the modern digital TV receivers are provided with
many advanced and sophisticated features such as stereophonic
sound, picture in picture, intelligent remote control and recently,
the manufactures are launching in the market apparatus using
LCD screen instead of the traditional image tube.
Such enormous technological evolution arisen in the last 70
years is well illustrated through a pictorial sequence of the
most representative types of the television receivers.
