I strongly believe that advertizing junk and unhealthy food should be prohibited. Doctors say that junk food leads to obesity and serious diseases. Children like it because it looks nice and smells nice. But they are not aware of the danger.
Some people may think that such a ban on junk food advertisement is a violation of rights. It also poses danger to freedom of speech and mass media, they may think.
But I consider that our nation's health is more important. So we must do all we can to teach people to choose healthy food for themselves and their children. Results of scientific research in this field should be made public. So the people will finally make the right choice!
До 1891, звонки были положить через операторов по обмену, но это было сделано с Канзас-Сити человека, который изобрел систему с прямым набором, потому что он был параноик, чтобы думать, что операторы посылали его деловые звонки конкурентам. Он был владельцем похоронного бюро.
В 1927 году первый трансатлантический звонок был сделан через радиоволны. Во время обеих мировых войн, телефоном достижений рос как на дрожжах из-за больших затрат на Министерство обороны. Инновации в результате военных экспериментов в комплекте Белл Телефон первая система сотовой телефонной связи, которая соединяла движущихся транспортных средств на стационарные телефоны через радио. Удивительно, но это было уже в 1946 году, в год, что также видели развитие коаксиальных кабелей для передачи основных улучшений с меньшим вмешательством.
В 1960 году, телефоны были столь же неотъемлемой частью пейзажа, что Белл Телефон больше не могли продолжать использовать буквенно-цифровые коды для телефонных станций (помните, с номера, как Нормандия-7610?) и переключился на дольше, все числовые номера. В то же время, трансатлантические кабели были проложены с учетом увеличенного спроса на межконтинентальной телефонной связи. Одним из важнейших сдвигов в истории телефона был запуск первого спутника телефон в июле 1962 года. Telstar был совместным предприятием между Bell и NASA и революцию в телефонной связи, как будто ничего, что надо было приезжать раньше. Спутники на геостационарной орбите могут использоваться для междугородних звонков без необходимости прокладывания бесконечных линий кабельных и покончил с проблемой частого повреждения кабеля и ремонт .
