is the
English-language news and information
Radio Network of the publicly-owned
Canadian Broadcasting Corporation . It is
Commercial free and offers both local and national programming. It is available to ninety-eight percent of
Canadians , and is also available overseas through
Radio Canada International and also over the
Internet .
A modified version of CBC Radio One, with local content replaced by additional airings of national programming, is also available on
Sirius Satellite Radio channel 137. It is downlinked to subscribers via both
Sirius Canada and its U.S.-based counterpart,
Sirius Satellite Radio .
CBC Radio began in
1936 , and is the oldest branch of the Corporation. In
1949 , the facilities and staff of the
Broadcasting Corporation Of Newfoundland were transferred to CBC upon
Newfoundland And Labrador 's entry into
Canadian Confederation .
Beginning in
1944 , the CBC operated two English language radio services, the original network became the ''
Trans-Canada Network '' and a new network, the ''
Dominion Network '' was established with
CJBC in Toronto as its flagship.
With the exception of CJBC, all 35 stations on the CBC Dominion Network were privately owned affiliates, its programming tended to be lighter than that of the Trans-Canada Network and carried more American programming in its schedule. As well, the Dominion Network operated only in the evenings freeing affiliates to air local programming during the days.
In
1962 , the Dominion Network was dissolved and within a few years CJBC became a French-language station broadcasting the programming of
Radio-Canada .
In
1960 , the CBC began running distinct programming on its three existing
FM English language stations, which were previously providing simulcasts of programming on its AM stations. The stations, located in Toronto, Ottawa and Montreal, broadcast a monoaural FM signal. Programming consisted mostly of classical music. The stations were linked by CN/CP Telecommunications via land-line and microwave. This service was discontinued in
1962 , but resumed in
1964 in stereo. Eventually, a national satellite-distributed network of stereo FM stations was established. In
1975 , the FM network was branded ''CBC Stereo'', and the AM service was designated ''CBC Radio''.
CBC Radio stopped running
Commercial Advertising in
1974 .
In the
1990s , many of the CBC's AM stations moved to FM, meaning that the old distinction between the AM "Radio" network and the FM "Stereo" network was no longer accurate, even though many of the FM "Radio" stations broadcast in mono only. As a result, in
1997 the services were rebranded with ''CBC Radio'' becoming CBC Radio One and ''CBC Stereo'' becoming
CBC Radio Two . By
2007 , four of Radio One's remaining AM stations,
CBX Edmonton,
CBK Saskatoon,
CBW Winnipeg and
CBR Calgary will have FM transmitters to simulcast the AM programming.

Until early 2007, CBC Radio One promotional spots were announced by Canadian actress
Shauna MacDonald , also known as "Promo Girl". Until fall
2005 , promos ended with one of two slogans: either "Because sometimes a picture needs a thousand words" or "Hear the big picture".
Some CBC Radio One programs, such as ''
Definitely Not The Opera '' and ''
As It Happens '', also air in the
United States on some stations associated with
American Public Media . Some CBC-SRC programs are relayed on Radio Canada International for listeners abroad.
Although each Radio One station broadcasts to a large geographic region through a network of
Rebroadcasting transmitters, only stations which are licenced as separate broadcast undertakings are listed here. Rebroadcasting frequencies are noted in each station's separate article. Most of these stations are primary (that is, stations which directly produce at least one
Local Program ), while other stations' local programming simply consists of local news updates.
Two CBC Radio One stations,
CFGB in
Happy Valley-Goose Bay, Newfoundland And Labrador , and
CBU in
Vancouver, British Columbia , operate shortwave relay transmitters, which use the
Call Sign s of CKZN and CKZU respectively. Both transmitters broadcast 1 kW
ERP signals on a frequency of 6160 kHz, and are difficult to receive in their intended target areas due to increased terrestrial noise from modern electrical and electronic systems.
Some have
suggested that CBC/Radio-Canada create a new high power shortwave
Digital radio service for more effective coverage of isolated areas. However these coverage plans will be slowed by CBC/SRC near-term plans for new
ATSC television and
Digital AM Radio transmitters.
Most schedules include hourly news readings that run from 6-12 minutes on the top of the hour except for major programming like the 6 p.m. news show and ''Cross Country Checkup''. Some mid-day programs include only brief 90-second "information updates".
The Radio One feed on
Sirius Satellite Radio has no local programming, and repeats other shows in time slots that would normally occupied by local programming. It carries the first feed of ''
The World At Six '' at 6 p.m.
Atlantic Time (5 p.m.
Eastern Time ), and also carries ''
The World At Six '' in its last airing at 6 p.m.
Pacific Time .
In the summer months of July and August, some programming is temporarily shortened and/or replaced by special summer series. During the CBC's recent labour dispute, most of the following schedule was temporarily replaced by a mix of repeat airings of recent CBC programs,
BBC World news programming and music from the CBC service
Galaxie .
Stations in the Canadian territories air a significantly different schedule with expanded local programming that includes a number of programs in local
Aboriginal languages. They still air most, but not all, of the core CBC Radio One schedule, although some programs may air in abbreviated versions. See
CBC North for further information.
On
January 17 ,
2007 , the CBC announced some changes to the network's schedule to begin in April. Among them, ''
Freestyle '' and ''
The Arts Tonight '' will be merged into ''
Q '', a new afternoon arts magazine to be hosted by
Jian Ghomeshi , ''
Global Village '' will be discontinued and some of its features merged into ''
Dispatches '', and ''
Between The Covers '' will move exclusively online.

Reasons given for the schedule changes are said to be based on audience research, however some negative reaction has been seen, especially regarding the evening programming changes.
