  1. History In The Media By: Nicholas Keough

  2. Typewriter • A typewriter is a mechanical or electromechanical machine for writing in characters similar to those produced by printer's type by means of keyboard-operated types striking a ribbon to transfer ink or carbon impressions onto the paper.

  3. Newspaper • The news paper was for delivering news back in the day. This was in vented by Johann Gutenberg in 1447. A newspaper typically generates 70–80% of its revenue from advertising, and the remainder from sales and subscriptions. Newspapers have, in the modern world, played an important role in the exercise of freedom of expression

  4. Radio • The radio was later invented too deliver news and everyone could get the news for free. This was invented in the 1940’s. The meaning and usage of the word "radio" has developed in parallel with developments within the field of communications and can be seen to have three distinct phases: electromagnetic waves and experimentation; wireless communication and technical development; and radio broadcasting and commercialization.

  5. Radio • One of the first developments in the early 20th century was that aircraft used commercial AM radio stations for navigation.

  6. Internet • The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite to link several billion devices worldwide.  It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless, and optical networking technologies.

  7. Cable • Cable had been invented in 1948. In time, cable television was widely established to carry available Canadian stations as well as import American stations, which constituted the vast majority of signals on systems.

  8. Cable • During the 1970s, a growing number of Canadian stations pushed American channels off the systems, forcing several to expand beyond the original 12-channel system configurations.

  9. Digital • Digital television is the transmission of audio and video by digitally processed and multiplexed signal, in contrast to the totally analog and channel separated signals used by analog television. It is an innovative service that represents a significant evolution in television technology since color television in the 1950s

  10. Satellite • Satellite television is television programming delivered by the means of communications satellite and received by an outdoor antenna, usually a parabolic reflector generally referred to as a satellite dish, and as far as household usage is concerned, a satellite receiver either in the form of an external set-top box or a satellite tuner module built into a television set. Satellite television tuners are also available as a card or a USB peripheral to be attached to a personal computer.
