Context: On October 9, 2006 at 6:00 a.m., the network switched to a 24-hour schedule, becoming one of the last major English-language broadcasters to transition to such a schedule. Most CBC-owned stations previously signed off the air during the early morning hours (typically from 1:00 a.m. to 6:00 a.m.). Instead of the infomercials aired by most private stations, or a simulcast of CBC News Network in the style of BBC One's nightly simulcast of BBC News Channel, the CBC uses the time to air repeats, including local news, primetime series, movies and other programming from the CBC library. Its French counterpart, Ici Radio-Canada Télé, still signs off every night.
