Television

In my opinion I think that television is very important a useful and perfect a thing device for  people.Because of this reason, many people can watch anything, such as news,weather condition,magazine,sport news film and documentary.Also I learned about John Baird life.He was invented television in 1925.In addition, television is very useful and very popular device for people in the world.Because of nowadays people can use TV with other devices such as play station or DVD player.In conclusion,I think television is very useful device  but in my suggestion for people they should control their time because  I think that they should not watch TV much

Could you tell me what about  thing television?
