 * 1) In year 1926, J.L. Baird first displayed television which had only 30 lines and gave coarse image. Currently the digital signal of the television sends pictures with 1080 lines.
 * 2) A 103-inch plasma TV from Panasonic is the largest plasma TV currently available in the market, costing approximately around $70,000.
 * 3) The television advertisement first broadcasted on 1st July, 1941 in New York. The advertisement was for Bulova Watch for 20 seconds. It was aired before a game of baseball played between the Philadelphia Phillies and the Brooklyn Dodgers.
 * 4) To understand how television works, you need to know about light, sound, and electromagnetic waves. Simply put, a television camera turns the light and sound of live action into pulses of electricity that are transmitted from the television station in waves, and are then received by your television.
 * 5) When the program is broadcast, the electronic signals are sent to the station's transmitter. Here, the signals are converted to electromagnetic waves. This transmitter first produces a powerful carrier wave onto which both the video and audio signals are placed.

=3 Advantages of using the radioactive isotope/radiation/benefits of discovery= =Is the radioactive isotope/radiation/discovery still used today? Explain=
 * 1) Television and video are the most powerful communicative tools in history. Video allows you to communicate your message quickly and effectively, while holding your viewers' interest.
 * 2) Producing a sales video often costs no more to produce than a high-quality 4-color brochure. What's more, one of video's major advantages is its ability to give a great deal of information in a short amount of time. A well-scripted, 8 -minute video can give as much information as an entire stack of print materials!
 * 3) Video saves time, because the message can be presented more quickly. A recent study conducted by Pennsylvania University's Wharton School of Business discovered that video speeded-up buying decisions by 70%.
 * Yes it is, because it helps us comunicate and keep in touch with the world.
