Television now and then

Television has become a common communication receiver since it is commercially available in late 1930’s until now days. Television has trough so many revolutions since back then and until now the process is still continue. I have made a research about the revolution of the television and compare the television back then and now. There are some similarities and differences between the televisions now and then.
Even though there are big time boundaries between the televisions back then and now and through so many revolution but there are still some similarities between the television now and then. The first similarity is both of them have a plug in speaker. The user does not have to use the earphone to listen the sound. The second one is television is still using a button. The button is use for adjust the channel, adjust the volume, or to power on and power off the television. The third one is the revolution of television do not make a change the usage of electricity as the source to run the television. This is because the electricity is the cheaper and the easier source that user can get in this world until now.
The big time boundaries have made the television now days have so many differences since back then. First difference is the television back then use the fish bone antenna and now days the antenna has been change to the parabola antenna. The fish bone antenna have weak transmission signal that can only receive one or two channel in a time but it is different situation by using the parabola antenna that have a strong transmission signal that can retrieve thousand of channel in a time. Secondly the user of the old television have to change the channel or adjust everything by push the plug in button on it while now day user just have to push button on the remote control. The invention of remote control have make the user can change the channel from far away. The third one is the screen of the television only can display only white and black color while now day with plasma screen we can see full color movie with the high quality of picture. Next difference is with the new technology now day the thick shape of the old television has been upgrade with more slim and nice look.
As the conclusion, television now days is more sophisticate compare to the television back then. This is because television is number one information device in the world. The revolution of the television is a must to make sure the information are send effitionly.
