The Fifth Estate

The Fifth Estate (usually branded in all-lower case 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 16, 1975, and its primary focus is on investigative journalism. Stories from The Fifth Estate routinely make headlines in Canada and have been regularly exported to other television networks around the world.
