TELEVISION:

Television is an amazing machine which people can communicate ideas to other people from different places. This media is changing our world every day. So, I have chosen the communication channel to write about it because this technology is very important in our lives.

Television history came into being bused on the inventions and and discoveries of many scientists, but Ferdinand Braun was the first one who invented the television. The first generation of television sets were not entirely electronic. The TV screen had asmall motor with a spinning disc and a neon lamp, which worked together to give a blurry reddish orange picture about half the size of a business card. The period before 1935 is called the "Mechanical Television Era". This type of television is not compatible with today's fully_ electronic television system.
