The television remote control may not be among the greatest inventions of the 20th century, but it certainly is one of the more convenient ones. Gone are the days when you had to stand in front of the television and surf channels by turning a dial or pressing buttons. However, remotes are not just for TVs anymore, and virtually all modern video devices come with a remote of some kind. Most TV remotes usually control only the television or sometimes a DVD player or VCR made by the same company.

Before you can use a remote control with most devices, though, you must program it using special manufacturer remote codes. Writer Bio
