Broadcasting is the distribution of audio and/or video content to a dispersed audience via any electronic mass communications medium, but typically one using the electromagnetic spectrum (radio waves), in a one-to-many model. Broadcasting began with AM radio broadcasting which came into popular use starting with the invention of the crystal detector in 1906. Before this, all forms of electronic communication, radio, telephone, and telegraph, were "one-to-one", with the message intended for a single recipient. The term "broadcasting", borrowed from the agricultural method of sowing seeds in a field by casting them broadly about, was coined by either KDKA manager Frank Conrad or RCA historian George Clark around 1920 to distinguish this new activity of "one-to-many" communication; a single radio station transmitting to multiple listeners.
Over the air Broadcasting is usually associated with radio and television, though in practice radio and television transmissions take place using both wires and radio waves. The receiving parties may include the general public or a relatively small subset; the point is that anyone with the appropriate receiving technology can receive the signal. The field of broadcasting includes a wide range of practices, from relatively private exchanges such as public radio, community radio and commercial radio, public television, and commercial television.
Fractured signs, they waste my time,
they concentrate, they take what's mine,
lost they move like fractured ghosts,
to empty heads in empty lines.
Trapped in frames of empty films,
a war is flat, in frames they kill,
light will char and edits cut,
they broadcast stare-
they know they must.
Faded raids before they fold
into themselves
it's done I'm told,
acting last repeats to last
and beats you back
when credits rolled.
Build yourself a fame through fire
and douse it out
when you require,
list your age on lilac page
strength in a crawl
back to the stage.
When it's obvious they're not scared of us
they will drag you back to cold,
all film burnt at source, much too fast of course
they will drag you back for more
when your wish runs out they will make you doubt
they will drag you back for more
when your frame runs dry minds will start to fly
they will break before they fold.
Broadcasting once
Broadcasting twice
Broadcasting one two three four five.
