Free-to-air refers to television or radio broadcasting that is accessible to the general public without any subscription or pay-per-view fees. There are several synonyms for free-to-air, including over-the-air (OTA), broadcast television, terrestrial television, non-subscription television, and freeview. OTA broadcasting typically uses a network of transmission towers to send signals to anyone with an antenna capable of capturing those signals. Broadcast television is a term often used to describe the reach of television networks in general. Terrestrial television refers to television transmissions that are sent through the airwaves rather than a cable or satellite service. Freeview is a brand of digital terrestrial television in the UK that uses OTA broadcasting.
