Cable television is a system of delivering television programming to consumers via radio frequency (RF) signals transmitted through coaxial cables, or in more recent systems, light pulses through fibre-optic cables. This contrasts with broadcast television, in which the television signal is transmitted over-the-air by radio waves and received by a television antenna attached to the television; or satellite television, in which the television signal is transmitted over-the-air by radio waves from a communications satellite orbiting the Earth, and received by a satellite dish antenna on the roof. FM radio programming, high-speed Internet, telephone services, and similar non-television services may also be provided through these cables. Analog television was standard in the 20th century, but since the 2000s, cable systems have been upgraded to digital cable operation.
Dual-tone multi-frequency signaling (DTMF) is a telecommunication signaling system using the voice-frequency band over telephone lines between telephone equipment and other communications devices and switching centers. DTMF was first developed in the Bell System in the United States, and became known under the trademark Touch-Tone for use in push-button telephones supplied to telephone customers, starting in 1963. DTMF is standardized as ITU-T Recommendation Q.23. It is also known in the UK as MF4.

Nathan Beverly Stubblefield was an American inventor best known for his wireless telephone work. Self-described as a "practical farmer, fruit grower and electrician", he received widespread attention in early 1902 when he gave a series of public demonstrations of a battery-operated wireless telephone, which could be transported to different locations and used on mobile platforms such as boats. While this initial design employed conduction, in 1908 he received a U.S. patent for a wireless telephone system that used magnetic induction. However, he was ultimately unsuccessful in commercializing his inventions. He later went into seclusion, and died alone in 1928.
Charles David "Doc" Herrold was an American inventor and pioneer radio broadcaster, who began experimenting with audio radio transmissions in 1909.

Telephone numbers in Singapore, also known as the National Numbering Plan, are regulated by the Info-communications Media Development Authority (IMDA). Due to the small geographical size of Singapore, there are no area or trunk codes; all numbers belong to one numbering area, and thus come in the same 8-digit format. Numbers are categorised based on the first digit, thus providing ten possible categories, of which six are currently in use and the remaining four reserved for future usage.
The Pelham Park and City Island Railway was a short street railway in the Bronx, New York City, which connected City Island with the Bartow station of the Harlem River and Port Chester Railroad on the mainland. The line existed from 1884 to 1919, most of that time as a horse-drawn system. The mainland portion was converted to an electrically-driven monorail in 1910, unique in the country at the time, nicknamed The Flying Lady. Prior to the railway, a stagecoach operated between City Island and Mount Vernon.
Telephone Newspapers, introduced in the 1890s, transmitted news and entertainment to subscribers over telephone lines. They were the first example of electronic broadcasting, although only a few were established, most commonly in European cities. These systems predated the development, in the 1920s, of radio broadcasting. They were eventually supplanted by radio stations, because radio signals could more easily cover much wider areas with higher quality audio, without incurring the costs of a telephone line infrastructure.
The Telefon Hírmondó was a "telephone newspaper" located in Budapest, Hungary, which, beginning in 1893, provided news and entertainment to subscribers over telephone lines. It was both the first and the longest surviving telephone newspaper system, although from 1 December 1925 until its termination in 1944 it was primarily used to retransmit programmes broadcast by Magyar Rádió.

The United States Telephone Herald Company, founded in 1909, was the parent corporation for a number of associated "telephone newspaper" companies, located throughout the United States, that were organized to provide news and entertainment over telephone lines to subscribing homes and businesses. This was the most ambitious attempt made to develop a distributed audio service prior to the rise of radio broadcasting in the early 1920s.

Although a number of tests over telephone lines were made throughout Michigan from 1906 to 1908, and the company hoped to eventually expand nationally, it never advanced beyond the exploratory stage.
Araldo Telefonico was the name used for a group of telephone newspaper systems located in Italy, which provided news and entertainment programming over telephone lines to subscribing homes and businesses. Beginning with the capital city of Rome in 1910, this was the most widely implemented of the various telephone newspaper operations, however, in the early 1920s, the systems were merged with, and eventually superseded by, the development of radio broadcasting.
