Description
CS101 Chapter 4-Radio Week 4 Influence of Radio Ubiquity -Radio is everywhere. The signals carried on the electromagnetic spectrum to almost every nook and cranny -This was especially evident during the 2003 blackout when people turned their portable radios on to listen in. -“Radio is a perfect fit for modern life; it’s effortless, easy to listen to during other activities; entertains and informs throughout the day; is compatible with other media and provides a soundtrack for life”. -The audience is slipping from the traditional stations to iPods, direct to listener satellite services, webcasts and cell phones -Canadians aged 12-34 are listening to less radio than in the past Radio Technology Electromagnetic Spectrum -Energy waves on which radio messages are piggybacked. -As early as 1873, physicists speculated that the electromagnetic spectrum existed, but it was an Italian nobleman, Guglielmo Marconi, who made practical application of the physicists’ theories while living in Canada Transmitting Voices -In 1906, Lee de Forest, a promoter who fancied himself as an inventor, created what he called the audion tube to make voice transmission possible.

Provides quality sound, and much of it is commercial free. -Terrestrial-traditional name for over-the-air radio stations -iPod-handheld MP3 players which siphoned listeners from over-the-air local radio. People are able to create their own playlists -Podcasting-anybody who wanted to create a show could prerecord a batch of favourite music, complete with narration, as an audio file on a personal computer -Webcasting-many Canadian radio stations stream their signals on the web. Chain Ownership -in order to cut costs to maximize profits, big radio chains consolidated their new properties in the post- CS101 Chapter 4-Radio Week 4 1996 era and centralized not only playlists but also disc jockeys -Through a system called voice tracking, a handful of announcers can be heard on several radio stations, owned by the same company, in different markets. -Ex.
