Commercial television broadcasting is allocated frequencies that fall in the VHF and UHF bands. Table lists the television channel allocations in the United States, with the channel bandwidth of 6 MHz. In contrast to radio broadcasting, television signal-transmission standards vary from country to country. The U.S. standard is set by the National Television Systems Committee (NTSC). Commercial television broadcasting began as black-and-white (monochrome) picture transmission in London in 1936 by the British Broadcasting Corporation (BBC).Although color television was demonstrated a few years later, due to the high cost of color television receivers, color television signal transmission was slow in its development. With the advent of the transistor and microelectronic components, the cost of color television receivers decreased significantly, and by the middle 1960s, color television broadcasting was widely used by the industry. The NTSC color system is compatible with monochrome receivers, so that the older monochrome receivers still function receiving black-and-white images out of the transmitted color signal.
