Telecommunications or telecom is the transmission of signals over long distances for the purpose of communication. Telecommunication began in 1876 with the invention of the telephone. Thereafter, it expanded to radio broadcasts in the late 1800s and to television in the early 1900s. Telecommunication typically involves the use of electronic devices such as telephones, television, radio or computers. The modern telecommunications include the internet and cellular phone networks.
