ï‚ž   levision (TV) is
    a telecommunication medium for transmitting
    and receiving moving images that can
    be monochrome (black-and-white) or colored,
    with or without accompanying sound.
    "Television" may also refer specifically to
    a television set, television programming,
    or television transmission.
ï‚ž   The etymology of the word has a mixed Latin
    and Greek origin, meaning "far sight":
    Greek tele (τῆλε), far, and Latin visio, sight
    (from video, vis- to see, or to view in the first
    person).
ï‚ž   In its early stages of development, television
    employed a combination of optical,
    mechanical and electronic technologies to
    capture, transmit and display a visual
    image. By the late 1920s, however, those
    employing only optical and electronic
    technologies were being explored. All
    modern television systems relied on the
    latter, although the knowledge gained from
    the work on electromechanical systems
    was crucial in the development of fully
    electronic television.
ï‚ž   The first images transmitted electrically were
    sent by early mechanical fax machines,
    including the pan telegraph, developed in
    the late nineteenth century. The concept of
    electrically powered transmission of
    television images in motion was first
    sketched in 1878 as the telephonoscope,
    shortly after the invention of the telephone.
    At the time, it was imagined by early
    science fiction authors, that someday that
    light could be transmitted over copper
    wires, as sounds were.
ï‚ž   he idea of using scanning to transmit
    images was put to actual practical use in
    1881 in the pantelegraph, through the use
    of a pendulum-based scanning
    mechanism. From this period forward,
    scanning in one form or another has been
    used in nearly every image transmission
    technology to date, including television.
    This is the concept of "rasterization", the
    process of converting a visual image into a
    stream of electrical pulses.
ï‚ž Getting TV programming shown to the public can happen in
  many different ways. After production the next step is to market
  and deliver the product to whatever markets are open to using
  it. This typically happens on two levels:
ï‚ž Original Run or First Run: a producer creates a program of one or
  multiple episodes and shows it on a station or network which has
  either paid for the production itself or to which a license has
  been granted by the television producers to do the same.
ï‚ž Broadcast syndication: this is the terminology rather broadly used
  to describe secondary programming usages (beyond original
  run). It includes secondary runs in the country of first issue, but
  also international usage which may not be managed by the
  originating producer. In many cases other companies, TV
  stations or individuals are engaged to do the syndication work, in
  other words to sell the product into the markets they are allowed
  to sell into by contract from the copyright holders, in most cases
  the producers.
ï‚ž   Around the globe, broadcast television is
    financed by either government,
    advertising, licensing (a form of tax),
    subscription or any combination of
    these. To protect revenues, subscription
    TV channels are usually encrypted to
    ensure that only subscription payers
    receive the decryption codes to see the
    signal. Unencrypted channels are known
    as free to air or FTA.
ï‚ž   Television's broad reach makes it a
    powerful and attractive medium for
    advertisers. Many television networks
    and stations sell blocks of broadcast time
    to advertisers ("sponsors") in order to fund
    their programming
ï‚ž   Since inception in the U.S. in 1940[citation
    needed], television commercials have become
    one of the most effective, persuasive, and
    popular methods of selling products of many
    sorts, especially consumer goods. During the
    1940s and into the 1950s, programs were
    hosted by single advertisers. This, in turn, gave
    great creative license to the advertisersover
    the content of the show. Due to[citation
    needed] the quiz show scandals in the 1950s,
    networks shifted to the magazine concept
    introducing advertising breaks with multiple
    advertisers.
