广播电视的诞生有赖于现代电子技术的发展。而随着电子管向晶体管再向集成电路的不断进步,广播电视也得以不断完善:效果更好,更加廉价,拥有更多的用户群。然而,随着计算机及其网络技术在上世纪末的飞速发展,诞生了区别于传统报纸、广播、电视的“第四媒体”,随后又诞生了被称为“第五媒体”的手机。根据第十五次中国互联网络调查报告,目前我国的上网用户总人数已超过1亿,而其中有近一半是通过宽带接入互联网的。国际电信联盟(ITU)发表了一个预测:由于中国使用宽带上网的人数急速上升,中国将在近期超过美国成
The birth of radio and television depends on the development of modern electronic technology. With the tube to the transistor to the continuous improvement of integrated circuits, radio and television have also been continuously improved: the effect is better, cheaper, with more user base. However, with the rapid development of computers and their network technology at the end of last century, the “fourth media” different from traditional newspapers, radio and television was born, followed by the birth of a mobile phone called “the fifth media.” According to the 15th China Internet Survey, at present, the total number of Internet users in China has exceeded 100 million, of which nearly half are connected to the Internet through broadband.
