Rivi 46:
The development of television technology can be partitioned along two lines: those developments that depended upon both mechanical and electronic principles, and those which are purely electronic. From the latter descended all modern televisions, but these would not have been possible without discoveries and insights from the mechanical systems.
 
The word ''television'' is a hybrid word, created from both Greek and Latin. ''Tele-'' is Greek for "far", while ''-vision'' is from the Latin ''visio'', meaning "vision" or "sight". It is often abbreviated as '''TV''' in the U.S. and '''telly''' in the UK and Australia.msdkfmlgnmrdjfnowsmnsjnajsnaskjdakjsadäads
