Television stations are facilities that broadcast television programs to the public. They transmit signals over the airwaves or through cable and satellite systems, allowing viewers to access a variety of content, including news, entertainment, and educational programs. Each station typically operates on a specific frequency and may be affiliated with national networks like NBC, ABC, or CBS. These stations can be categorized into different types, such as commercial, public, and educational. Commercial stations generate revenue through advertising, while public stations, like those affiliated with PBS, rely on government funding and viewer donations. Educational stations often focus on instructional content and community programming.
