The development of transistor technology and the semiconductor industry enabled significant advances in telecommunication technology, led to the price of telecommunications services declining significantly, and led to a transition away from state-owned narrowband circuit-switched networks to private broadband packet-switched networks.
The history of communication itself can be traced back since the origin of speech circa 100,000 BCE. [1] The use of technology in communication may be considered since the first use of symbols about 30,000 years BCE. Among the symbols used, there are cave paintings, petroglyphs, pictograms and ideograms.

The timeline of radio lists within the history of radio, the technology and events that produced instruments that use radio waves and activities that people undertook. Later, the history is dominated by programming and contents, which is closer to general history .
1970: Amos E. Joel, Jr. of Bell Labs invented the "call handoff" system for "cellular mobile communication system" (patent granted 1972). 1970: British companies Pye TMC, Marconi-Elliott and GEC develop the digital push-button telephone, based on metal–oxide–semiconductor (MOS) integrated circuit (IC) technology.
