CHEX is one of the oldest broadcasting television stations in Canada. Founders included writer Robertson Davies and his father William Rupert Davies. The transmitter tower for CHEX Peterborough is on Television Hill on the east side of the city and is used to broadcast both television and radio.

The Peterborough Examiner is the regional daily newspaper, and one of the area's original local publishers. From 1942 to 1955, it was both owned and edited by renowned Canadian author Robertson Davies, who resided in the city. In the late 1980s, the tabloid-style Peterborough This Week entered the market, taking a large share of advertising away from the Examiner. Peterborough This Week is a free newspaper delivered to most homes in Peterborough County. Alternatively, Arthur and The Absynthe are student newspapers funded and produced by Trent University students. They are distributed at no cost on the university campus and in the downtown area. The first issue of The Wire Megazine was published in 1989. The tabloid continues to publish monthly and is one of the country's oldest independent alternative presses. It is free and available throughout the Kawarthas and enjoys a wide range of advertisers and readers.^{[citation needed]}
