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.

Baird died in Bexhill-on-Sea, Sussex, England on 14 June 1946. The old house was destroyed in 2007. The Sea Road-Station Road skyline now features a new block of 51 flats on the site, renamed "Baird Court". John Logie Baird is buried with his mother, father and wife in Helensburgh Cemetery, Dunbartonshire. Baird built what was to become the world's first working television set by purchasing an old hatbox and a pair of scissors, some darning needles, a few bicycle light lenses, a used tea chest, sealing wax and glue.

TV nowadays Recently, such a kind of TV has appeared, allowing to see deep volumetric image, without using stereoscopic or other glasses. In the future such a technology will be used in houses and for translation on the TV channels, and now rare copies are used mainly for advertising. From August 2009 Japanese TV channel BS11 3D broadcasts transmissions, supporting a three-dimensional image.
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.
