'''Coal''' is a [[Carbon|carbon-containing]] rock formed by the debris from the decay of ferns, vines, trees and other plants which flourished in swamps millions of years ago. Over time, the debris became buried and the actions of [[bacteria]], [[heat]] and [[pressure]] transformed the debris first into [[peat]] (a precursor of coal) and then into the various types of coal as we know them today.<ref name=Perry>{{cite book|author=Green, Don W. and Perry, Robert H.

Coal is extracted by [[mine (resource extraction)|mining]] from deposits that exist deep underground as well as deposits that are essentially at or near the surface of the ground. Because of the various degrees of transformation that occurred during the forming of coal deposits in different locations, the composition of coal varies from one deposit to another. No two coals are the same in every respect. In general, coal consists of [[carbon]], [[hydrogen]], [[oxygen]], [[nitrogen]], [[sulfur]] and [[mineral]] matter (including compounds of [[silicon]], [[aluminum]], [[iron]], [[calcium]], [[magnesium]] and others).<font size=1>[[Coal|['''more...''']]]</font>

'''Gasoline''' or '''petrol''' is a fuel, derived from [[petroleum crude oil]], for use in spark-ignited [[internal combustion engine]]s.

It has an initial [[boiling point]] at [[atmospheric pressure]] of about 35 °[[Celsius|C]] (95 °[[Fahrenheit|F]]) and a final boiling point of about 200 °C (395 °F).<ref name=FAQ>[http://www.faqs.org/faqs/autos/gasoline-faq/part4/ Gasoline FAQ - Part2 of 4], Bruce Hamilton, Industrial Research Ltd.

In [[Canada]] and the [[United States]], the word "gasoline" is commonly used and it is often shortened to simply "gas" although it is a liquid rather than a [[gas]]. In fact, gasoline-dispensing facilities are referred to as "gas stations".


Most current or former [[Commonwealth of Nations|Commonwealth countries]] use the term "petrol" and their dispensing facilities are referred to as "petrol stations". The term "petrogasoline" is also used sometimes. In some European countries and elsewhere, the term "benzin" (or a variant of that word) is used to denote gasoline.

Featured Article: Telephone newspaper/Citable Version

1901 photograph of a stentor (announcer) at the Budapest Telefon Hirmondó.
Telephone newspaper is a general term for the telephone-based news and entertainment services which were introduced beginning in the 1890s, and primarily located in large European cities. These systems were the first example of electronic broadcasting, and offered a wide variety of programming, however, only a relative few were ever established. Although these systems predated the invention of radio, they were supplanted by radio broadcasting stations beginning in the 1920s, primarily because radio signals were able to cover much wider areas with higher quality audio.

History

After the electric telephone was introduced in the mid-1870s, it was mainly used for personal communication. But the idea of distributing entertainment and news appeared soon thereafter, and many early demonstrations included the transmission of musical concerts. In one particularly advanced example, Clément Ader, at the 1881 Paris Electrical Exhibition, prepared a listening room where participants could hear, in stereo, performances from the Paris Grand Opera. Also, in 1888, Edward Bellamy's influential novel Looking Backward: 2000-1887 foresaw the establishment of entertainment transmitted by telephone lines to individual homes.

The scattered demonstrations were eventually followed by the establishment of more organized services, which were generally called Telephone Newspapers, although all of these systems also included entertainment programming. However, the technical capabilities of the time meant that there were limited means for amplifying and transmitting telephone signals over long distances, so listeners had to wear headphones to receive the programs, and service areas were generally limited to a single city. While some of the systems, including the Telefon Hirmondó, built their own one-way transmission lines, others, including the Electrophone, used standard commercial telephone lines, which allowed subscribers to talk to operators in order to select programming. The Telephone Newspapers drew upon a mixture of outside sources for their programs, including local live theaters and church services, whose programs were picked up by special telephone lines, and then retransmitted to the subscribers. Other programs were transmitted directly from the system's own studios. In later years, retransmitted radio programs were added.

During this era telephones were expensive luxury items, so the subscribers tended to be the wealthy elite of society. Financing was normally done by charging fees, including monthly subscriptions for home users, and, in locations such as hotel lobbies, through the use of coin-operated receivers, which provided short periods of listening for a set payment. Some systems also accepted paid advertising.
