Canadian Broadcasting Corporation

The Canadian Broadcasting Corporation (CBC) is a national television network in Canada, and is akin to the BBC in that it is primarily government-funded (although, unlike the BBC, the CBC also airs commercials).

Prior to relocating to the UK where he created series such as The Avengers and Doctor Who, Sydney Newman, a Canadian, worked for the CBC.

In 1964, the CBC became the first North American broadcaster of Doctor Who when it began airing the early William Hartnell-era stories, but the network cancelled its broadcasts after about a year.

In 2005, history repeated itself when the CBC hosted the North American broadcast premiere of the revived series, initially broadcasting the show only a couple of weeks after its UK telecast (and many months before American broadcasts of the revived series began). The CBC also received screen credit for contributing development funds towards the new series. The 2005 broadcasts were sponsored by TV Guide magazine, and Christopher Eccleston videotaped a series of introductions and "bumpers" in which he discussed the series and its characters and also promoted a contest run by TV Guide and the CBC, the first prize being a trip to Wales to visit the set of Doctor Who. Most broadcasts ended with a brief, Doctor Who Confidential-style look behind the scenes, and the CBC also compiled its own version of Confidential for its website. The CBC was criticised for editing episodes for length (due to the need to fit in commercials).

On December 26, 2005, the CBC aired The Christmas Invasion, one day after its UK showing. For this occasion, Billie Piper recorded special introductions and bumpers, wearing an outfit with the Canadian-iconic "Roots" logo.

In 2005, it was also announced that the CBC would co-produce the first season of Torchwood in much the same capacity as it did Doctor Who.

Beginning in 2006, broadcasts of Doctor Who became less timely on the CBC, as the broadcaster chose not to air the series until well after its broadcast in the UK, but still before the US broadcast. The second series was also interrupted (in-between the two-parter The Impossible Planet and The Satan Pit) by a lengthly mid-season break. As a result, the Canadian release of the 2nd Series DVD set actually occurred the week before the CBC broadcast the series finale.

In 2007, the CBC aired the third series of Doctor Who, again months after its UK airing, with the Christmas special, The Runaway Bride airing after the season premiere, Smith and Jones. Broadcast of the first series of Torchwood did not occur until after the third series of Doctor Who, even though the season finale of Torchwood led into the season finale of Doctor Who. The CBC aired Torchwood generally intact, except for censoring certain words of dialogue and making cuts for commercial time.

In 2008 it was announced that the CBC would no longer be funding Torchwood and would not air the second series. It was rumored that the CBC had also dropped its funding for Series 4 of Doctor Who, which was supported by the fact the CBC no longer received screen credit on Series 4 episodes, but the CBC later said it was still supporting the series. In May 2008, after months of speculation by Canadian fans, the CBC announced it would belatedly air the fourth series starting on September 19, 2008, months after the broadcast of the series in both the UK and US, and with an anticipated break at Christmas that will result in the season finale not airing until early 2009.
