In 1927 the first transcontinental telephone call was made, however this was only possible through broadcasting radio waves. In 1935 the first international telephone call was made, leading to the running of wires along sea beds to allow long distance communication. Later developments in technology including satellite communications allowed for increased volume and higher quality in these calls.

The design of the telephone has allowed the development of other forms of technology, in particular the internet. Originally [[dial up modems]] connected directly through the telephone system, and more recently [[ADSL]] which uses partitions of telephone lines (this in turn has led to [[Voice over IP]] or VoIP in which calls can be placed through an internet connection). [[Cellular phones]] were also developed from the fixed line network, and utilise similar technology when transmitting calls between base towers and exchanges.
