The idea that images and sound could be broadcast had its antecedents in wireless communication (radio) that was developed after the (wired communication) telegraph and the pantelegraph (early fax machine) were invented. The Selenium camera and the Nipkow disc led to the development of mechanical television and then, electronic televisions. In 1929, John Baird broadcast the first television program in England. Around the same time, in 1930, Philo T. Farnsworth was granted a patent for a television based on the cathode-ray tube in the United States. In 1939, Farnsworth launched his electronic television at the New York World's Fair and television as we know it was born. At first, there were only a few programs available, but after World War II interest in television, and in producing a wide range of programs for broadcast, grew. In 1953 the national magazine TV Guide was created. Color television did not become popular until programs began to be broadcast in color in the early 1960s. Subsequent developments in technologies, such as cable and satellite, as well as adaptations like closed-captioning, have helped to make television an essential part of daily life. Concluding chapters in this book review modern uses of the television in business and in the sciences and possible future uses of television. The graphics and photo-illustrations are well designed and help make the information easy to understand. The reader is directed to further research on the concluding page, which has a glossary and an index. This book would be a good addition to a middle school library or science center and would also provide a useful summary to an older reader. Part of the "Breakthrough Inventions"series.
