Gr 7 Up-A solid overview of the history of radio and television communications in the United States and the people involved. The introduction highlights the early pioneers, such as the well-known Samuel Morse and Guglielmo Marconi, as well as lesser-known innovators like Frank Conrad, who started the first commercial radio station in 1920. Chapters on later visionaries, such as David Sarnoff, founder of NBC, and Rupert Murdoch of the News Corporation, parent of Fox TV, reveal both personal and professional achievements. Two women are included: Catherine Hughes, who started the Radio One empire, a voice for the African-American community, and Judy McGrath of MTV fame. Color and black-and-white photos enhance the text, which, while not the most engaging, relays both the facts of the actual development of radio and television and the men and women behind it. Source notes and a lengthy index are appended.-Carol Fazioli, Gwynedd-Mercy College, Gwynedd Valley, PA Copyright 2006 Reed Business Information.
