  Biography of John Logie Baird
  John Logie Baird was born in 1888 near Glasgow. He had made money selling socks and soap. He sold off this business to follow his dream of inventing a television. It became an obsession and he had to borrow money from friends to survive and use whatever materials he could including scraps. By 1925, he was ready to give the first public display of a working television. The chosen place was Selfridges in Oxford Street, London. Shoppers saw slightly blurred but recognizable images of letters.
  First public demonstrations
  On 26 January 1926, Baird repeated the transmission for members of the Royal Institution and a reporter from The Times in his laboratory at 22 Frith Street in the Soho district of London. By this time, he had improved the scan rate to 12.5 pictures per second. It was the first demonstration of a television system that could broadcast live moving images with tone graduation.
  He demonstrated the world's first colour transmission on 3, July 1928.That same year he also demonstrated stereoscopic television.

  Role of television
  Television has always been a big part of our society. Every day as we are moving forward with our busy life, television is taking part in it. As our society is growing, the news media, sports, and entertainment are also expending themselves. Television is influencing our daily life in many ways. Its good parts are helping us to move forward in our life. On the other hand, television has a negative influence on society because it is seen more as an entertainment purpose, rather than educational. Therefore, it has lowered the overall moral standards. Television did not play any major role in peoples life in 20th century, it was a hope for people to have a television at their home, where today we have two or three televisions at the same house. This is an improvement of technology, but is this improvement of technology in television helping us or harming us? If the answer is not harmful, it would be very hard for us to say that it is helpful.
