Define "terrestrial broadcasting."

Terrestrial broadcasting refers specifically to the transmission of radio and television signals through the air via electromagnetic waves, which are then received by antennas. This method relies on ground-based transmitters to disseminate the broadcast signals to a wide audience, allowing users to receive the content using standard receiving equipment, such as indoor or outdoor antennas.

This approach is distinct from satellite broadcasting, which involves sending signals from satellites orbiting the Earth to dish antennas, and from wired connections, which utilize cables or fiber optics to transmit data directly. Terrestrial broadcasting plays a crucial role in providing accessible media to the general public, especially in areas lacking robust internet infrastructure or where satellite reception may be unreliable. Understanding this concept is fundamental for anyone studying radio operations, as it highlights the primary method of distributing broadcast content to listeners and viewers.
