Broadcast television refers to the television stations broadcast freely to television sets without paid service or special devices. Stations such as NBC, CBS, and ABC were among the first stations to air freely for viewers. These commercial stations are still available for free to television viewers within reception range.
Since regular broadcast stations have changed to digital broadcasting, individuals with analog television sets have to buy converter boxes. These boxes allow the digital channels to broadcast through the analog sets. Aside from the cost of a converter box, digital broadcast television is still free, and new television sets are equipped with the ability to air digital television.
Cable television, which has been around in some form since the 1940s, allows individuals to pay a fee for access to both broadcast stations that may be out of range and premium channels.
Although many people still watch broadcast television, cable television has become very popular because of the wider variety of choices. Cable companies usually offer several plans, some that include premium channels, such as HBO or Showtime. Cable requires the use of a cable box.
Satellite television, like cable television, often requires a device, usually a satellite dish and box, and has a monthly fee. Satellite television offers more viewing choices and allows viewers in remote or rural areas to have more options than basic cable.
