卫星电视：电视机的发明者是英国的电子工程师约翰·贝尔德，1923年他为自己发明的能产生8线图像的装置申请了专利。1930年底卖出了第一台电视机。1932年，英国广播公司播出了世界上第一个规范的电视节目。从此，人类开始步入了电视时代。今天，人们利用卫星等途径，将电视信号传播到地球的每一个角落。
电视当今世界上人均拥有量极高的电视（平均每10人拥有一部）
纵观电视的发展，可归纳为三个阶段：机械黑白电视、电子黑白电视、电子彩色电视。
机械黑白电视阶段
1848年，意大利的卡赛里发明了化学电传真系统，率先实现了用电的方法在阿米昂与巴黎之间进行远距离传送画面的奇迹。随后，电话的发明、硒光敏特性的发现都是进行电视研究的最早启蒙。各国科学家们迫不及待的想实现“用电的方法看到远处活动景象的愿望”。1884年，尼泼科夫首先取得了机械电视用扫描盘发明专利。此后，光电管、阴极射线管、真空二极管、三极管的发明为电视的诞生奠定了坚实的基础。
1920－1930年间，许多科学家提出并实验了用机械扫描方法实现图象信号的发送与接收的方案。故称此时为“机械黑白电视阶段”。在机械电视的研制方面，做出卓越贡献的是英国的贝尔德，他建立了世界上第一个专门研究机械黑白电视的实验室。他用简陋的设备组装成了世界上第一套电视发射机和接收机，并于1925年10月25日终于获得了电视传送的第一张真人图片，也就诞生了世界上第一台机械黑白电视机。
电子电视的兴起
从20世纪20－30年代，机械电视研究的同时，电子技术也开始迅猛的发展。美籍俄国科学家弗拉基米尔·科斯马·佐利金在这方面做出了重大贡献。他在1929年，试制成功了电子电视系统和电视显像管。1931年，又研制成功了电子摄像管，并于1933年取得了光电摄像管的专利。在此期间，美国的电视研究者之一，法恩斯沃恩于1927年取得了电子电视系统的专利。
1936年11月2日，在英国伦敦进行了第一次正式的电子电视系统的公开广播试验，当时用的是英国的休恩伯格研制的405行、每秒50帧的隔行电子扫描系统。此系统用的光电摄像管是在英国的麦吉尔领导下研制成功的。当时播放的电视图像的清晰度远远超过了机械扫描的电视，至此，电子黑白电视时代就开始了。
1939－1945年，由于第二次世界大战的爆发，延缓了电子电视的发展，当时，只有英、美、苏等少数国家建立了电子黑白电视系统。直到50年代初，世界各国才开始普及电子黑白电视。
我国于1956年开始筹建电视系统，1957年研制出第一套黑白电视发射机，1958年生产出了第一台黑白电视机，即天津产的“北京牌”电视机――仅有5个频道的电子管黑白电视机。
彩色电视的普及
彩色电视的研究始于1925年，当时佐利金、贝尔德等人都从事过这方面的研究，并做出了一定的贡献。因为20－30年代重点是电子黑白电视的研究，所以彩色电视机的研究主要在40－50年代才开始蓬勃发展。

Satellite TV: Television's inventor is Britain's electronic Engineer John · Baird, in 1923 he could have 8 graph alike installments for his invention to apply for the patent. at the end of 1930 has sold the first television. in 1932, British Broadcasting Corporation has broadcast in the world the first standard television program. Henceforth, the humanity started to march into the television time. Today, the people use ways and so on satellite, disseminates Earth's each corner the television signal. the television in the world the average per person capacity high extremely television (average every 10 people have one) to look over television's development now, may induce is three stages: Machinery black-and-white television, electronic black-and-white television, electronic color television. machinery black-and-white television stage the 1848 year, in Italy's Kasai has invented chemistry telephotography system, took the lead to realize the method which used electricity carries on the long-distance range transmission picture between Arab League Mi Ang and Paris the miracle. Afterward, telephone's invention, the selenium photosensitive characteristic discovery are conduct the television research the earliest initiation. Various countries' scientists impatient want to realize “the method which uses electricity to see the distant place moving scene the desire”. in 1884, Nepal sprinkled Shinao first to obtain the mechanical television to use the scanning disc patent of invention. Hereafter, the electric eye, the cathoderay tube, the vacuum diode, triode's invention has laid the solid foundation for television's birth. the 1920-1930 year, many scientists proposed and test have realized the image signal transmission and the receive plan with the mechanical scanning method. Thus is called this time is “the machinery black-and-white television stage”. In mechanical television's development aspect, the one who makes the outstanding contribution is Britain's Baird, he has established in the world the first special study machinery black-and-white television's laboratory. He used the crude device group to fit out in the world the first set of television transmitter and the receiver, and has obtained the first Zhang Zhen person picture which finally in October 25, 1925 the television transmitted, was also born in the world the first machinery monochrome set.
The television by electronic method started from the 1920s-1930s, mechanical television research's at the same time, the electronic technology also started the swift and violent development. American nationality Russia scientist Vladimirsky · Kosma · assisted the interest to make the important contributions in this aspect. He in 1929, trial produced the successful television by electronic method system and the video tube. in 1931, also developed successfully the emitron, and has obtained emitron's patent in 1933. , One of US's television researchers, law graciousness Si Wearn has obtained the television by electronic method system's patent in 1927. the 1936 year on November 2, has carried on the first official television by electronic method system's public broadcast experiment in the British London, what at that time used was Britain's Shoenberg develops 405 line, each second 50 interlacing electronic scanning system. This system uses under the emitron is leads in Britain's Mcgill develops successfully. At that time broadcast television image's clarity has gone far beyond the mechanical scanning television, hence, the electronic black-and-white television time started.
1939-1945 years, because the Second World War's eruption, delayed television by electronic method's development, at that time, only then UK and US, Soviet and so on some countries have established the electron black-and-white system. Until the early 50s, various countries only then started to popularize the electronic black-and-white television. our country started in 1956 to prepare for construction the television system, in 1957 developed the first set of black-and-white television transmitter, in 1958 produced the first monochrome set, namely Tianjin produced “the Beijing trademark” the television - only to have 5 channel electron tube monochrome sets. color television's popularization the color television's research began in 1925, at that time assisted interest, Baird et al. to be engaged in this aspect research, and has made certain contribution. Because the 20s-30s key point was the electronic black-and-white television's research, therefore color TV set's research mainly only then started the vigorous development in the 40s-50s.

Satellite TV: TV is the inventor of electronic engineers in the United Kingdom Baird, in 1923 he invented for himself to produce 8-ray imaging devices to apply for a patent. By the end of 1930 sold the first TV. In 1932, the BBC broadcast the world's first standard TV. Since then, human beings started to enter the television era. Today, people use satellite channels such as television signal will spread to every corner of the earth.

TV per capita in the world today has a very high volume of television (an average of every 10 people own a)

Throughout the development of television can be summed up in three phases: black and white television machinery, electronic black-and-white television, electronic color television.

Mechanical black-and-white TV stage

In 1848, Italy's Karzai in the invention of chemical Fax electric system, taking the lead in realizing the power of the method with Ami Ang in Paris between the long-distance transmission of images of a miracle. Subsequently, the invention of the telephone, the photosensitive properties of selenium are found in the study of television's earliest enlightenment. States can not wait for scientists to realize the "power of the method to see distant scenes activities of the desire." In 1884, Nigeria has made the first splash Alexander mechanical scanning disk television patents. Since then, phototube, cathode ray tubes, vacuum diode, the invention of the transistor to the birth of television has laid a solid foundation.

In 1920-1930, many scientists and experiment with a mechanical image scanning method to send and receive signals. At this point it is said to "mechanical phase of the black-and-white television." In the development of mechanical television, made an outstanding contribution to the Baird of the United Kingdom, he established the world's first research laboratory machinery black-and-white TV. He used the simple assembly of the equipment has become the world's first set of television transmitters and receivers, and in October 25, 1925 finally won television's first live transmission of images, it gave birth to the world's first mechanical Black-and-white TV.

The rise of e-TV

From the 1920s and 1930s, the study of mechanical television, electronic technology have begun to rapid development. Russian-American scientist Vladimir Cosma Zolli In this regard, Kim made a significant contribution. In 1929 he, a successful trial of electronic television systems and television picture tubes. In 1931, and the successful development of the electronic camera tube, in 1933 and made optoelectronic control of the camera patents. In the meantime, the U.S. television one of the researchers, Ensiwoen law in 1927 made electronic television system patent.

November 2, 1936, in London for the first time an official of the electronic system of public television broadcasting the trial, when used in the United Kingdom is the development of the Shoenberg 405 lines per second of 50 e-interlaced scanning system. The system uses optical camera control in the United Kingdom under the leadership of the McGill successfully developed. At that time the television broadcast images of the far-resolution machinery to scan more than a television, now, electronic black-and-white TV era began.

In 1939-1945, due to the outbreak of World War II, slowed the development of electronic television, at that time, only Britain, the United States and the Soviet Union and a small number of countries have established electronic black-and-white television system. Until the early 1950s, countries around the world began to popularize electronic black-and-white TV.

China in 1956 began to build television system, in 1957 developed the first set of black-and-white television transmitters in 1958 produced the first black-and-white TV, that is, the Tianjin production of "Beijing card" TV - only 5 channels The black-and-white TV tube.

Color TV popularity

Color television study began in 1925, when Kim Jolly, Baird and others are engaged in studies in this area and make some contribution. Because the 20-30 age focused on the electronic black-and-white TV, color TV so the study in the 40-50 age began to flourish.
