The Scotsman John Logie Baird invented television in the 1920s, by bringing together the work of some others, notably Paul Nipkow, who invented a spinning disk used to scan the image.
The first public demonstration of television was in a department store, Selfridges, in London England, by Mr Baird himself. This took place in 1925. The system was successful enough to become commercialised, and the BBC began the world's first regular television broadcasts, using the Baird system, in 1936. By 1939, there were over 20,000 TV sets in use in and around London. A year later, in 1940, baird demonstrated a set which was capable of receiving colour pictures and stereo sound!

In 1921 the 14-year-old Mormon had an idea while working on his father's Idaho farm. Mowing hay in rows, Philo realized an electron beam could scan a picture in horizontal lines, reproducing the image almost instantaneously. This would prove to be a critical breakthrough in Philo Farnsworth's invention of the television in 1927.
Earlier TV devices had been based on an 1884 invention called the scanning disk, patented by Paul Nipkow. Riddled with holes, the large disk spun in front of an object while a photoelectric cell recorded changes in light. Depending on the electricity transmitted by the photoelectric cell, an array of light bulbs would glow or remain dark. Though Nipkow's mechanical system could not scan and deliver a clear, live-action image, most would-be TV inventors still hoped to perfect it.
Not Philo Farnsworth. In 1921 the 14-year-old Mormon had an idea while working on his father's Idaho farm. Mowing hay in rows, Philo realized an electron beam could scan a picture in horizontal lines, reproducing the image almost instantaneously. It would prove to be a critical breakthrough.

You should be able to research this question yourself. The point of homework is to do the work yourself so that you learn from it. Go to google.com or yahoo.com and do a search for the first television set. I'm sure you'll find tons of useful information to use in your report. Also, don't rely on people on Yahoo answers to give you truthful answers to your homework questions.
