The Fifth Estate (stylized as the fifth estate) is a Canadian television newsmagazine, which airs on the English language CBC Television network. The name is a play on the fact that the media are sometimes referred to as the Fourth Estate, and was chosen to highlight the program's determination to go beyond everyday news into original journalism. The program has been on the air since September 1975, and its primary focus is on investigative journalism. It has engaged in co-productions with the BBC, The New York Times, the leading Canadian newspapers The Globe and Mail and The Toronto Star, and often with the PBS series Frontline. - Source: Wikipedia
